Did you write/save the partition table after your changes? Did you reboot thereafter? I make some suggestions below but they come with the health warning attached that I have no responsibility if it doesn't work. > Here is my outpu from > # fdisk -l > > fdisk -l > > Disk /dev/hda: 60.0 GB, 60011642880 bytes > 255 heads, 63 sectors/track, 7296 cylinders > Units = cylinders of 16065 * 512 = 8225280 bytes > > Device Boot Start End Blocks Id System > /dev/hda1 * 1 1913 15361888+ 7 HPFS/NTFS > Partition 1 does not end on cylinder boundary. This is in itself is not a problem. If you create/resize partitions based on MB you may or may not hit a clean cylinder boundary. Do your resizing in cylinders and the end result will coincide with their boundaries. > /dev/hda2 1914 4208 18427027+ c W95 FAT32 (LBA) > Partition 2 does not end on cylinder boundary. > /dev/hda3 5100 7296 17637480 f W95 Ext'd (LBA) > Partition 3 does not end on cylinder boundary. Look what has happened here, your extended partition starts at cyl 5100, while your first logical partition starts at cyl 4208. I'd say that neither are correct. I suggest that you resize your extended partition hda3 to start at cyl 4209, i.e. straight after the end of the previous primary partition (hda2). > /dev/hda4 4208 5099 7164990 83 Linux Here you need to change the beginning of this partition to be straight after the end of the previous primary partition and at the beginning of the extended partition. So, hda4 should start at cyl 4209. > /dev/hda5 * 5100 5108 68008+ 83 Linux This is good, but you do not need the boot flag. As a matter of fact it may confuse your WinXP bootloader and Linux does not need it. > /dev/hda6 5108 5173 521608+ 82 Linux swap / This is not good as it overlaps the end of the previous partition. hda6 should start at cyl 5109. > Solaris /dev/hda7 5173 7296 17047768+ 83 Linux > > Partition table entries are not in disk order That's because they were created at a chronological sequence which do not reflect their physical order on the disk.

In that case reformat them and use your back up to restore the data. An alternative approach is to restore your partition table to a previous version and with it the previous boundaries of your partitions. After I was faced with a borked partition table too, I used testdisk to recover and restore previous partition table entries. http://www.cgsecurity.org/wiki/TestDisk HTH. -- Regards, Mick
