Hi, I installed Slackware 12.0 on a IBM Thinkpad with 50 GByte sata drive. Lilo was installed to the superblock of the Linux root partition, /dev/sda3. I get a warning about lba32 addressing. That partion was made bootable. When I try to boot, I get "operating system missing". Now, when I copy 512 bytes from /dev/sda3 to a file on the windows partition and mention that file in window's boot.ini, mark the windows partition bootable, I get a boot-dialog on rebooting and after selecting Linux, I get the expected Lilo prompt and everything works fine from there. Any idea, why I cannot directly boot from the linux partition? The only unusual thing (fdisk warns about this) is that the partions are not in the sequence as they are numbered: 1. NTFS /dev/sda1 2. linux, root /dev/sda3 3. linux, swap /dev/sda4 4. VFAT /dev/sda2 /dev/sda2 is a windows rescue partion and I didn't dare to move it around. Could this be the problem? Or is this a ThinkPad peculiarity?

Didn't the Slackware installer recognize Windows was there? : If it did, it would have configured LILO to boot both OSes. Right now, : there's a Windows' MBR on the hard drive, and Windows doesn't recognize : or even acknowledge the existence of other OSes, and so won't boot them. : Stef Installing on a Linux partition has worked for me many times, just this ThinkPad has the problem. (I use Linux since 1995 on dual boot computers and never ever installed in the MBR). Windows should not at all come into the play, as the Windows partition is not marked bootable, but the Linux partition is. The notebook may be 2 years old; so the partition size limitation should not apply. So it must be either a bios or a lilo problem. -- -ulrich
