Dual-boot laptop won't boot either (long)

Dual-boot laptop won't boot either (long)

Post by Mandrake 7 Use » Sun, 31 Dec 1899 09:00:00

My laptop came with Windows 95 (which worked fine) and I wanted to make
dual-boot with Linux-Mandrake.  Now it does not boot any more at all.
the details:

I used fips to shrink the Win partition and then fdisk (or cfdisk, I'm
sure; that was months ago now) to create Linux and swap partition.

The first problem appeared right away: Win95 would not boot any more.
never has since then.  I can't reinstall it since the laptop has no CD

So I went ahead with installing Linux in the empty partitions.  After
weeks of aggravation (caused by the need for a network install, since
there's no CD drive) that finally worked.  Linux was finally
installed, configured and personalized.

Finally, after setting up booting with LILO (in the MBR) and including
entry for Windows I wanted to see if Win95 would work again.  It did
of course.  LILO would try to load it, and no part of Win95 would ever
load.  So I thought I'd try a DOS bootsector in the MBR.  After all, I
can always boot Linux from floppy, and then rerun lilo.  Or so I
After "FDISK /MBR" from a DOS floppy, Win would still not boot.  I
thought, "OK, forget Windows for a few months and put LILO back in."

And then the trouble began.  Linux would not boot any more either.  I
used the
bootdisk made with mkbootdisk.  It offers to boot from /dev/hda6 (rather
since there are only 3 partitions), then loads linux from floppy
anyway.  Then
after some activity without access to floppy or HD, it detects the HD,
sees the
correct number of partitions thereon (3), and hangs about 1 second

The last messages on the screen are:

autorun ...
... autorun DONE.
attempt to access beyond end of device
03:06: rw=0, want=2, limit=0
dev 03:06 blksize=1024 blocknr=1 sector=2 size=1024 count=1

isofs_read_super: bread failed, dev=03:06, iso_blknum=16, block=32
Kernel panic: VFS: Unable to mount root fs on 03:06

When I boot in to a floppy-distro of Linux (HAL91 in this case), I try
to see
the Linux partitions but no luck:

$ mount -t ext2 /dev/hda3 /linux
VFS: Can't find an ext2 filesystem on dev 03:03.
mount: wrong fs type, bad option, bad superblock on /dev/hda3,
       or too many mounted file systems

On the other hand, mounting Windows that way works:

$ mount -t vfat /dev/hda1 /windows
$ df
Filesystem    1024-blocks  Used Available Capacity Mounted on
/dev/root          3019    2264      602     79%   /
/dev/hda1        253920  -42328   296248    -16%   /windows
$ ls /windows

And "ls" and "more" display the Windows files correctly.  Which is
since with the Windows bootdisk I cannot get to the Windows files or
even the
partition.  The funny "-16% used" seem to indicate a problem though.
Maybe the
partition table is corrupt?

Here is the fdisk output (Linux fdisk):

Disk /dev/hda: 64 heads, 63 sectors, 525 cylinders
Units = cylinders of 4032 * 512 bytes

   Device Boot    Begin   Start      End    Blocks   Id  System
/dev/hda1   *         1       1      127    256000+   6  DOS 16-bit


/dev/hda2           262     262      524    758016   83  Linux native
/dev/hda3           733     733      148     42336   82  Linux swap

That fdisk output looks fine to me.

Can anyone figure out what's wrong with this laptop?  Maybe the
partition table
is corrupt?  And what steps can I take to recover without reinstalling?

1. Sparc 20 won't boot and won't display errors, either.

Take the video card out and see if that helps - I had a system recently that
would not do anything because of a bad video card.
