LILO can't boot Win7?


I loaded Slackware 14 on /dev/sdb1, Win7 was already on /dev/sda1 and was bootable before Slackware install using previous install of lilo.

Now, when I boot, Linux boots fine, Win7 reports BOOTMGR missing, ctrl-alt-del to reboot. lilo.conf contains:

boot = /dev/sdb
change-rules
reset
other = /dev/sda1
label = Windows
table = /dev/sda

image = /boot/vmlinuz
root = /dev/sdb1
label = Linux
read-only

Thanks in advance for assistance.

What is the output of
Code:
fdisk -l
For a quick fix you can try to change sda1 to sda2 in the windows entry rerun lilo and see if that helps

Windows comes often with a boot partition and some systems have also a recovery partition (all NTFS), you should have the windows-boot partition in your lilo.conf

I'll change lilo to point to /dev/sda2 and report shortly.

Changing lilo to point to /dev/sda2 reports:

File: \Windows\system32\winload.exe
Status: 0xc000000f
info: The selected entry could not be loaded because the application is missing or corrupt.

Thanks in advance.

You have four Windows-partitions. Is Windows really installed on /dev/sda1 and /dev/sda2? If it's installed on /dev/sda, the boot partition is probably /dev/sda2 because it's the smaller one.

Well, it would be good if you knew on which partition(s) your Windows is installed.

BTW: my lilo.conf looks like
Code:
# Windows bootable partition config begins
other = /dev/sda2
  label = Win7
  table = /dev/sda
# Windows bootable partition config ends
Maybe you'll change the entries for Windows in your lilo.conf.

Fortunately, I do know where windows is installed, /dev/sda1, with the system reserved partition on /dev/sda2. Perhaps had you read my posts, you would have seen that. I do know why I would change the lilo.conf to agree with yours; is it because the label is different, or that they point to different partitions? Anyway, thanks for looking, wish it was helpful.

problem could be the BIOS device numbering at boot time. Maybe Windows remembers the numbering from when it was installed, or it has certain undocumented expectations. This theory can be tested by installing LILO in /dev/sda and changing the boot device in the BIOS.

Btw, are you sure you need the "change-rules reset"?

Is your Win 7 installation using UEFI and GPT by chance? If it's an x86_64, very likely yes...
Have a look here in case

Determine the partition Windoes is installed on using parted. Then point LILO to the bootable partition.
Win7 normal install tends to create 3 partitions. A rescue partition (dev/sda1), a boot partition (dev/sda2) and a user partition (dev/sda3) Parted wil show what you have and which is marked bootable.

Where did you install LILO? why on the first sector of the second disk? (boot=/dev/sdb)

Thanks for the suggestions. First, I was able to save the \Users directory onto USB drive. Then installed Win 7 onto an NTFS partition on another drive. When bootmgr came up, I selected the second Windows 7 entry and the original Windows 7 came up. Whew. Never saw installing lilo breaking an existing Win 7 installation, been using linux since 1.2.8. Turns out the original Win7 install was, in fact, on /dev/sdb2.
