Vista and error 0xc0000001 after removing infections


New Member
Hello all. New to this forum Fixing a Toshiba A305 laptop for a student of mine. Was heavily infected. Product key was unreadable but "keyfinder" gave me the key. Now in a boot loop with the unexpected code 0Xc0000001. Tried multiple fixed including rebuilding the BCD from scratch, multiple times doing startup repairs (never finds anything), etc. and always returning to the 0xc0000001 error. Can't get past it. No restore points on this accessible but found 2 entries under system volume info. Hard drive is readable. Anyone had this experience? Is it related to the SAM?
