[Need Help] "Missing operating System"

Hi all,
I don't know if my problem as already been solved but I didn't found anything.
At first, I have to say I installed windows 8 as principal operating system (I know, it's stupid...).
I used windows 8 without big problem since the deployment but today, after a bug, I reboot the PC and now I have just black screen with the message "operating system missing"... The system does not boot, just black screen with the message
Does anybody have an idea how I can solve this problem ?
(Sorry for my english)

you can put dev preview DVD or USB whatever you used to install.
and run the installation and then repair Windows 8 (if it detects a Windows installed). with system restore or maybe it will repair. if not you will have to refresh your win8.
also it can be (if you have more hard drives) that you aren't starting the one with Windows 8. so you can try and see in bios if thats the case. thats when i have seen this message.

Thanks for your answer.
When I run the pc, it doesn't launch anything, just the black screen. It's probably the bios but I can't do anything, just the message but I'm not allowed to do anything :-(

Finally, the problem is quite solved.
When I have this message, by pushing ctrl+alt+suprr, if I'm enough fast, I can push F12 and choose wich part I want to run. Then I placed my W7 backup on CD and runned it.
It was not easy but W7 is successfull restored.
Of course, all my personal data were deleted...
But whe I reboot the PC, I've always the message "missing operating system", then I have to ctrl+alt+suprr and after F12, and then choose the hard drive, and the PC W7 boot.
It's not yet perfect but for the moment the PC works...

Thats exactly i told you. of course it changes between bios and motherboard. your problem is not your windows. its the priority of your harddrive.
I dont know what motherboard you have.
so i will find pictures to explain what you have to look for. because you didnt have to repair your Windows if thats the case. the problem its (like i mentioned) your harddrive priority.
so you go to your bios and look for the Boot section.

if you go to Boot Device Priority, you can check if your harddrive is second (the one with your OS) and if you want your cd or usb to boot first if not you can leave it first.

something like this.
and if that part is right you have to go to Hard disk drives
http://www.laptops-battery.co.uk/images/maintain/bios-boot-hard-disk-drives-445x261.jpg
so there you have to check if your harddrive is first or the correct one. and ready... its probably this Hard disk devices thing. and then you don't have to use that method of changing manually which boots

Thanks for your help
I'm not at home for the moment. I'll try your method tomorrow or wednesday, I'll let you know, but thank you for the time you spent on my problem.

[Q] Window 8 wont boot up!!

Help would be great. I have a dell inspiron laptop (not sure exactly what model it is) and I made the mistake of downloading windows 8 consumer preview when it first came out and installing it directly on the laptop rather than dualboot or usb stick. It worked fine for a couple of days and then out of nowhere it wouldn't boot up. When I press the power button the screen will light up and the w8 logo will appear but it won't go past that part. Sometimes It will say auto repairing itself but I've left it on for two days to see if it would fix itself but It didn't. Is there a way to get in safe mode to atleast re install the iso file? I've been without a laptop for a couple of months already and can't afford to buy a new one!

so am I correct in thinking you have no installation media at all for windows? any version?
If so do you have access to another PC because to be honest, your probably going to need it
I assume you have tried hitting F8 on boot to get to the boot menu and that didn't work either?
in terms of your hardware its cool, that's not the issue, the software is, having an install disk would have made things a lot easier....

Yes I have access to another pc and no I don't have any available. I downloaded a newer version of the win8 in ISO format and put it on a dvd disc and tried installing it through the f12 key right when you boot up. The disc drive started running but nothing happened afterwards. Windows recently released a new version of win8. Should I download that one and try it again the same way I tried the first time?

ok, you hit F12 to get in to the boot menu is that correct? then you selected the DVD drive and it made some noises but did nothing?
Ok, Boot menus can be troublesome
What I suggest is go in to the BIOS and change the boot order to DVD first THEN HDD, if that doesn't work then take the HDD out of the boot order altogether, you will need to turn it back on again though to complete the setup
also, I want you to see if the DVD boots on another computer, the first ISO I downloaded was corrupted and whilst mine booted it would always fail to install, re downloaded it and no problems at all
Its probably worth downloading the RP ISO anyway, the previous version the CP, was mass tested in the open market so any issues with installing wouldn't have been worked out in the CP, hopefully the RP would have got most of them,

Hi, i did what you recommended and it worked fine until the install process! It took me to the install screen and i pressed install. Afterwards it gave me the option of automatically doing the install or choosing custom options only. I choose the automatic and it told me that i had to remove the disc and restart the computer and re inster the disc for it to continue! The problem is that everytime i do that it wants to boot up the original way where it wouldnt work! Any ideas. Should i choose the custom option instead ( but i dont know what to choose if i do it that way)??!! Thanks for your help

Reload and options

HI!
Yes, you are right.
Boot to the install media, at the option to do custom, select custom.
When the screen loads showing the partitions (drives)
-Click advanced on the bottom right
-highlight each partition and delete them (this will loose all data saved there but unless you have a boot disk or usb or remove the drive from the laptop, the data is usless anyway)
At this point you can click continue, or next Windows setup will auto create the partitions it needs and unpack the files, then finish install.
If you get any issues with files missing or media is corrupt from the ISO, you will need to down load it again, use the MS download manager or some manager to ensure the download is good and the file CRC matches what they have on the download site. I have seen this a lot lately so don't waste your time restarting the install if it has an error while coping files, just get a new download.
I hope this Helps.

This does resemble a copy error, or even a hard disk/hard disk controller problem.
I have a desktop computer that will no longer boot up from any IDE devices (even if their properly formatted, it also includes any optical medium), Trying to boot from them results in a "DISK NOT BOOTABLE" (something around that, Acer's boot errors are different from the usual ones.
Anyway, back on track, before all that happened, I had trouble booting the computer from the IDE HDDs, sometimes it would boot and sometimes it stuck at the Windows 7 loading screen till it said a file was corrupt or missing, or it BSOD'd.
I also recommend re-downloading and trying the install again, in extreme cases, if you have another HDD to test, try installing it on a different HDD. If that works, the problem could be your hard disk (or something more nefarious, who knows ^_^

Need help, venue 8 pro missing hard disk error. possible windows re-installation?

Hello guys, my brother had this tablet for a short period of time and he upgraded it to windows 10, everything was fine but then he wanted to revert back to windows 8.1 so he wiped everything. After that nothing worked, he kept getting a partition error (missing partition) and could not do anything about it. He gave me the tablet in hopes of fixing it so i got a fresh copy of windows 8.1 from the microsoft downloader and put it on a pen drive. I also used to tool to make it into a bootable storage space and even injected the drivers from the CAB from the dell website using NTlite, but every time i start the setup the touch screen doesn't work (so i used a keyboard) and it also says media driver is missing. When i start the tablet without the usb i get missing hard disk error and can only access the BIOS and diagnostics check (shows no errors there).
This community has helped me before, hopefully they can help me again because i can't seem to wrap myself around the problem

Backup any data that you don't want to lose and store it somewhere other than on your laptop's internal storage. Then download the hardware drivers(including any BIOS updates) for your specific laptop and the drivers for any other external hardware that you use with the laptop. Then do a complete format and reinstallation of Windows 10 using a Windows 10 .iso. Then reinstall your laptop's hardware drivers, starting with your chipset drivers, then video and audio drivers, then the rest of your laptop's various hardware drivers, then drivers for any external hardware that you use with the laptop.
Then you can copy your backed up data back to your laptop.

If you reinstall the system, you need to enter the license key. Even if you rolled back or transferred Windows to a new laptop, you still have to enter the key. When I bought a new PC I had to completely transfer the system to the new PC and consequently change 7 to 10 windows. I re-downloaded drivers, all necessary applications, installer packages. But then it wouldn't start because the system failed. My laptop has a new boot system that has been changed and it was not possible to just run windup from a flash drive. I bought the windows 10 pro key separately and entered it to activate all the packages. Everything worked.

Unable to install widows on new pc build

Hey guys,
I build a new pc, first new build in 20 years.
I’m using an ASUs tug gaming x670e plus WiFi motherboard with and 7800x3d cpu.
I’m stuck with the windows installation from usb.
First attempt I used a SanDisk 8gb stick and windows media creator. That’s right load, but looking back that was probably because of bios settings.
second attempt I used a leef 16gb stick. Art the verify stage at 99% it failed.
Third attempt save stick same method created the usb successfully. Had to pay around a lot with bios settings to get the stick seen as bootable. But during the windows installation it reported a file inaccessible or missing. Soo I put the stick in another machine to check but the file in question was there.
Soo I tried again, but now it cannot start up from the usb stick.
I’m in progress of creating an iso usb using the 8gb SanDisk drive, but I think I’m missing something significant.
I’ve attached my bios settings for booting.
If anyone can give some clarification, that would be greatly appreciated! If I can’t die this tonight I’ll bring it in a shop this weekend (just for a windows installation, sigh)

This... happy hunting.
Make a cloned copy of the disk once loaded and configured but before adding data, antivirus or trashware with Acronis to a spare hdd for easy OS restore.
*Redundantly backup critical data, first*
Separate data drives + OS drive are best plus the backup drives that are physically and electronically isolated from each other and the PC.

Managed to get an install.
Had to change a few bios settings (apparently one of the videos I watched for the right bios settings was the exact opposite of what was needed). Agassi used an iso stick.
That seemed to do the trick.

Thanks for the suggestions. It’s much appreciated.
I managed to get things installed. My issues were a combination of bad luck with my usb drives (and how the bootable stick was generated), as well as some poor advice on YouTube that told me the opposite of what was needed.
I also had problems obtaining an activation key legally, but that got resolved as well, so I finally managed to get my pc up and running.
Thanks again for the suggestions!
