An HP desktop has me my way 'in trouble'. After an initial poke I decided the easy way out is to save files to a pen drive and use the 'restore' mode.
On boot up the HP start screen gives F numbers for BIOS/restore(f11) etc.
So f11 was pressed ----and nothing happened
Looking at 'my computer' and looking into 'D' revealed an empty drive with a request to insert medial looking into all other 'drive' letters --builtin multi card reader--showed all the ''recovery files residing in 'G'
So. Wruill renaming 'G' to 'Do' bring things back to normal or is there some thing more sinister afoot?
When your computer boot into the recovery menu it does not read the drive the same way as Windows so changing the drive letter wouldn't make a difference.
Have you changed the size of the partitions on the drive, if so this can sometimes prevent the recovery from working. Another possibility is a corrupt file preventing the recovery from working properly.
Did you created a set of recovery disks? If you have use the recovery disks as these hopefully will reset the drive and restore the computer back to factory default.
