HELP!: Lost LILO after reinstalling Win95

Post by sri » Sat, 25 Dec 1999 04:00:00



Hi,

I had posted a request earlier for help with my LILO problem. I
reinstalled Win95 and overwrote the MBR (and thus lost LILO and access
to Linux 6.0 that was running on my PC).

I got replies from two people Jim and Anita. Thanks for your replies.

I followed their suggestions and tried to boot my pc with linux.
I was unable to. My original problem was because of a bad floppy disk (?)
giving me an error message 0x10.

I then downloaded an image file from redhat and created
a boot diskette using rawrite. With this, I was able to type "rescue"
at boot prompt and get the machine to read the floppy and
go through the bootup process. However, it stopped with a message:
.
.
.
md driver 0.90.0 MAX_MD_DEVS=256, MAX_REAL=12
Partition check:
hda: hda1 hda2 <hda5> hda3
hdb: hdb2 hdb3
VFS: cannot open root device 08:32
kernel panic: VFS: Unable to mount root fs on 08:32

 08:32 Does that mean anything?

I tried the command "linux hd=/dev/hdb3" (also linux hd=/tmp/hdb3)
at boot: prompt, where /dev/hdb3 is the linux native partition.
This did not help as the boot floppy put me into an installation setup.

Is there anything else I can do? Or, am I doing something wrong at
the very basic level? Unfortunately I do not have the installation CDs
as I had borrowed a friend's copy and I do not have access to it again.

If my disk parititioning information can be of any help I have included it
below:

I was able to get this information using an old installation CDs I got from

Infomagic.

Hoping to hear from the Linux Guru's!

You are using the RH6.0 installation floppy image, it appears.
Then at the boot: prompt
linux root=/dev/hdb3
should work.  If not
vmlunuz root=/dev/hdb3
should work.

If neither of these work---although I can't imagine why they
wouldn't---just boot again from the floppy and proceed as if
you were installing.   After a while and before you actually
do anything, Alt-F2 should give you a bash prompt.  You are
now running a Linux kernel from a ramdisk.  Try
mkdir /a
mount /dev/hdb3 /a
/a/sbin/lilo -r /a
sync
umount /a
and then reboot
What you would be doing is making a mount point, mounting your
root partition on it and then running the lilo in your root
partition with a relative root being the mount point.

You need a '/' before the 'dev'.

1. HELP!: Lost Linux after reinstalling Win95

Hi,

I was cleaning up folders in Window's 95 on my desktop computer
when I accidentally deleted system files. After this  Window's 95 refused
to boot.

I had installed LILO so that I could boot with Linux (RedHat 6.1),
optionally.
Window's 95 was my default operating system.
I created system disks from my other Windows'95 based computer
(a laptop) and re-installed it on my desktop.  After I this, I was able
to boot properly with Window's 95 but was unable to get the LILO prompt
or to boot into Linux. I have a linux boot diskette but the computer
refuses
to boot with it.

If any of you had encountered this problem before and was able to resolve
it, I would appreciate it if you would let me know of your solution.

thank a lot,
regards,
Sri
