Hey guys ive had a similar issue
i have a Dell Inspiron 1721 about a year old now.
i left it on doing some scans for a hour or so and came back to a blue screen, not good but not uncommon or anything but it said
IQNL_IS_LESS_OR_NOT_EQUAL
ive never seen this befor but it has being described as a hardware problem so i rebooted the system and it then rebooted into startup repair, it did its thing and i sent the error report, and went for a restart. it looked to boot fine and then went to the vista loading screen and then back into startup, i went through again and then realised that all the system restore points have gone.
we have tried diferent OS systems that boot from a CD to locate the Harddrive and get some realy important files off the HD, we have tried vista,linux,xp and mac os and we cannot find either of the Hardrives to mount or search
in the end i could only get some realy small files off using the system registry in the startup repair
we have come to the conclusion that all the boot files have being lost therfor is going into statup repair.
i have two 160gb hd drives that are RAID'ed so i cannot get into them too put them into another computer, oh and their both sata drives.
if anyone can help it would be much apreciated.
