Drive letter randomly changed, OS wont boot
Sadly I had to join here due to a problem with my 2 week old win 7 64 install.
I'm not sure what the trigger was but my C drive where my os is installed apparently took the drive letter of an external drive that I use for backup. It is now the X drive and I cannot boot. I do get the repair screen but cannot repair as there is no operating system to choose. Booting from windows disk makes no difference here.
My bios (uefi) can see the disk, I can also see it from the command prompt, Im at a loss what to do, any help is appreciated.
I believe this happened after an automatic windows update.
