Tried both method 1 and method 2 with the same result: installation fails while loading Windows NT filesystem (ntfs.sys). Nice BSOD says that windows is shut down to prevent a damage of my computer, blah-blah-blah, run chkdisk /f. CHKDISK says that there are no problems. ntfs.sys on setup disk has the same date and size as the one on the working OS. Could anyone help me? PS. BSOD says "*** STOP: 0x0000007B (...)", so I tried to use a modified ntdetect.com as it was advised above. Result is the same however.
