Windows 7: startup repair loop, root cause: no hard drive detected

11 Nov 2012   #11


Check in BIOS setup if you have an EFI Boot disk in the Boot Priority Order. If so you have EFI BIOs which requires special steps to install to a GPT Disk: UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums

If you want to install normally to MBR disk then remove the EFI Boot disk from boot order, enable any Legacy BIOS setting, clean HD again to remove GPT formatting, try install again.

If that fails, try formatting an Active partition from Step 2.2 here: SSD - HDD Optimize for Windows Reinstallation

If the HD does in fact disappear from any of these operations then test it using HD Diagnostic extended CD scan, followed by Disk Check from installer Command Line on full disk partition you create from step 2.2 above.

So using the UEFI to boot seemed promising at first following that tutorial, two things happened though. Following the step to clean all in diskpart, whilst cleaning it suddenly said error device not connected. Then I could no longer see my HD even though it was showing seconds before. After that I restarted to see if it still showed in BIOS and it didn't so I restarted again and it showed up so then I began the windows setup and it showed the disk as all unallocated space no partitions, so like the tutorial said I clicked "new" and it seemed to be working at first, then all the sudden it stopped in the middle of what it was doing and of course showed that there was no hard drive detected. So it seems as though my HD is a ghost, coming and going as it pleases and randomly disappearing without cause. **** me right? Oh and now that I restarted after that last disappearance, I can't even start the setup again. It just sits at a black screen after the starting windows screen displays, the cd drive ceases activity and it just does nothing now every time I restart it, I can set BIOS back to defaults all I want now and it doesn't help. Do I just have a screwed HD? Nothing I do helps, and it seems the things I've tried have showed good results for others so idk what I'm doing wrong.

Do you have an EFI BIOS? I told you how to check but you didn't reply for sure.

I also told you how to test your HD which appears indicated if WIn7 install causes that behavior when tried by both methods given.

Right but I can't perform those checks without first passing this black screen bs. Guess ill have to take out the HD for the third time and connect it to my desktop once more to do these checks. Thanks for your help so far, ill reply when I muster up the motivation to crack this ****er open again.

The tests are all done from boot disks.

Another note, I was able to create a partition earlier following the "optimize for windows installation" steps and again got an error message during setup that said it was unable to create partition. And idk if its an EFI BIOS or not how do I tell? When I tried to delete an EFI boot option it just said select one to delete nothing else, and wouldn't let me select anything.

In my first post I said to check if there is an EFI boot disk in BIOS boot order, that this means you have an EFI BIOS.

If you cannot install in EFI mode using the tutorial provided, then remove the EFI Boot disk from BIOS boot order by moving the DVD drive first to boot, followed by HDD.

You may also need to look for another setting in BIOS setup for Legacy BIOS to enable to complete this process. Then Save settings changes and Exit BIOS.

Now you need to run Diskpart Clean command again to assure you have not formatted HD as a GPT disk.

Why did you do a clean? You should have been able to rescue your files.
If it had a recovery partition it's gone.
If you were supplied with Windows install discs or made recovery discs then that would be an option.
