System Fails To Boot After 6.0 => 7.1 Upgrade
Last modified: 2007-04-18 12:33:35 EDT
Description of Problem:
I upgraded from RH 6.0 to RH 7.1 and chose all the default options, installing the LILO boot record on the MBR, the boot image on what I
assume to be the boot partition which in my case was /dev/hda7 (the only choice available), and creating a boot disk. When rebooting,
immediately after BIOS installation where LILO normally kicks off, the following two lines are displayed:
These two lines are repeated every 4 seconds, ad infinitum.
I repeated the upgrade with the same results. I am, however, able to boot into the system using the boot diskette that was created during the
Try upgrading from 6.0 to 7.1 on similar hardware. My hardware is an AMD K6-2 450mhz based system.
Steps to Reproduce:
1. Acquire similar hardware and install RH 6.0
2. Upgrade to RH 7.1, using default choices
Boot into the system using the boot disk you made, then run the lilo command and
seeif it returns any errors. If not, that *may* solve your problem (I'm not
sure what the BIOS error code 0x40 means, it could mean a failed read which
would indicate a drive that has a bad sector and re-running lilo to rewrite that
sector might make it work).
Unfortunately, this did not solve the problem. I booted with the boot diskette and ran the lilo command which had the following output:
Added linux *
Removing the diskette and rebooting produced the same results as initially described.
From LILO's docs:
0x40 "Seek failure". This might be a media problem. Try booting again.
I tried booting again. In fact I've tried rebooting several times. The same "0x40" error message appears every time. I also tried performing the upgrade
It sounds like a failure on the first sector of the drive for me... have you
continued to have problems with newer releases?
