In the past month or so, I've had a number of failed attempts at installing Paragon software, each resulting in a BSOD. Not sure if this isrelated, but after the failed attept, I am unable to boot to the partitition in which I had attempted to install th ePatagon software. My system is multiboot wit 4 Windos OS as folllows: Drive 1: C-D, OS on C Drive 2: F-H, OS on each of F and G Drive 3: I=M, OS on J Drine 4: S-T and Ubuntu, no Windows OS. I tried to install the Paragon software in G and F. Afte rtrybg G, I could not boot to G, The start up got stuck in a loop, likely because drive letters were screwed up. I fixed G by going back to a clean G, which restored the drive letters. Last night, I tried installing on F. Guess what, same problem, drive letters are likely screwed up. My boot.ini has: I've heard that there is a way to fix drive letters either via the Recovery Console, or via a remote registry. Pointers on how to do this? In the meantime, I'll try restoring an older version of the F drive.
