I installed linux on apartition of 7GB using text installation and fdisk instead of diskdruid because diskdruid limited the size of each partition to 4GB maximum.
I installed the PC with dual boot: winnt and Linux. When the system boot up, it only see Linux at the boot time. I was surprise that the system did not see the NT partition. I added the winnt in /etc/lilo.conf: ap=/boot/map install=/boot/boot.b prompt timeout=50 linear default=linux image=/boot/vmlinuz-2.2.14-5.0 label=linux read-only root=/dev/hda3 other=/dev/hda1 label=winnt table=/dev/hda Then boot it again and the system still cannot see the winnt partition. This is my disk patition table: Disk /dev/hda: 255 heads, 63 sectors, 1245 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 319 2562336 7 HPFS/NTFS /dev/hda2 320 344 200812+ 82 Linux swap /dev/hda3 345 1245 7237282+ 83 Linux I can see that in my first Linux PC (I used diskdruid) the patition table has an extended partition the size of the entire Linux file system. This is my first PC's partition table: Disk /dev/hda: 255 heads, 63 sectors, 1245 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 392 3148708+ 7 HPFS/NTFS /dev/hda2 393 1245 6851722+ 5 Extended /dev/hda5 393 802 3293293+ 83 Linux /dev/hda6 803 835 265041 82 Linux swap /dev/hda7 836 1245 3293293+ 83 Linux You can see on the second one, I used fdisk and there is no extended partition. All partitions on the second PC with problem are primary. Do you have any ideas what is wrong with the setup? How can I make my PC see both operating systems without reinstall it? Thank you, Daisy
