HELP HELP HELP!!!!
I screwed up my MBR and I'm now on my way to recover
things back to normal.
What I had:
1st HD
Boot manager
C: dos primary (100meg)
E: Extended logical HPFS with warp on (300meg)
2nd HD
D: extended logical HPFS
F: Extended logical FAT bootable from boot manager (small
maintenance partition)
Story so far:
With norton diskedit I found where everything was.
I restored C: with no problems, restored bootmanager
parition too. Though I had to re-create bootmanager
because it was partly over written.
Found where my HPFS partition started. To be exact, DOS
partition ended on cyl 100, side 63, sector 32. on cyl
101,0,1 there was a partition table as there is with
extended partitions. and at 101,1,1 (cyl,side,sect)
started the HPFS volume with boot sector.
If I write on MBR that the HPFS partition type is
extended and that it starts from 101,0,1, OS/2's FDISK
thinks there is no partition. If I write on MBR that the
partition is HPFS and starts from 101,1,1, OS/2's FDISK
thinks the partition as primary (which it wasn't), finds
also an unknown partition (I think it's the thing that
starts from 101,0,1). But I Can't boot from that HPFS
partition.
Even If I mark the HPFS partition as the only partition
on disk, primary and bootable, my system doesn't even
start booting. (top left corner doesn't get eaten).
with this configuration and boot from floppy and try to
access C: (which it shows on fdisk) gives sys0026: the
disk cannot be accessed.
Any HELP! Appreciated.
