Windows 7: What is x:(boot) drive?

30 Mar 2013   #31

w7 Home premium WoW64

I'm repairing a laptop for a friend. their laptop is a Toshiba that they purchased from BestBuy.

Pressing F6 (i think it was) during boot would open up to a pre-boot diagnostic menu that runs out of an X:/ drive.

A myrid of small programs are available at this screen including a DOS prompt.

I used this to run a chkdsk on C drive as you can not do that while booted.

This X:/ partition is a Pre-BIOS enviroment and is built into the computer.

win7 Home 64 bit

I know this is old, but thought this may help, and at the same time help me. I too, have the X: but it seems to be my Blu ray drive that is somehow partitioned off? Was having an issue with a bad SSD drive, and I noticed after messing around with that SSD that I now have Windows files on X:, which in my BIOS shows up as my Bluray drive. I show that I have 2 Bluray drives in BIOS when i only have one. Does this make any sense?

I have a Windows 7 install on a 60gb SSD (assigned to C: in Windows), and a 3 other drives just for storage, and programs. Windows will only boot if the SSD is the only one plugged in. BCD lists this as my only entry, and is calling the C: drive to boot. However when I load my Windows cd, this...

Moved boot manager, 7 drive still refuses to boot without old drive.
I've been trying all day to get to a point where I can format my old hard drive (D). I found out today that, in its infinite wisdom, the Windows 7 installer put the boot manager on a completely separate drive from my new drive (C), the one I selected for installation. Windows 7 is totally...
