Problem booting off USB stick
Posted: Thu Jul 25, 2013 1:54 pm
A slightly odd one this. I'm migrating my Win7 installation from my old FitPC2 to the FitPC3. Since I have to do a sysprep I decided to clone the main HDD to a spare drive and effectively 'recover' the drive to spare media before monkeying with it.
Anyway here's the sequence I used:
1. Backup main HDD to external drive.
2. Swap out main HDD for spare HDD
3. Boot off recovery media and restore to spare HDD.
4. Reboot, run sysprep etc. etc.
5. Reboot and go through 'New installation process'.
Up to now all is good. In fact it's all done and running. However I now want to put everything back on the main HDD and I've found something odd. The machine will no longer boot off my USB stick unless I also unplug the external drives. If the external drives are plugged in I just get 'Invalid partition table'. I've checked and neither of the external drives has an active partition so I'm stumped.
It may be that the recovery console will detect hot plugging of external drives so I could unplug them, boot, then plug them in. But that's a pain even if it actually works. If I can't boot off the recovery media I don't have a viable backup solution. Obviously it's something that happened while Windows 7 was completing installation but I can't see what.
Does anyone have any ideas?
