This happened to me, too. I first noticed it after upgrading, recently, to Ubuntu 10.04 from 9.10. I decided I wanted to go from dual-boot (with WinVista) to single-boot (Ubuntu 10.04 only). I opened GParted, and it showed my disk, /dev/sda, as wholly "Unallocated Space." Same thing when I tried booting from a GParted Live CD and from an Ubuntu 10.10 Live CD.
I have not lost any data, but it is very frustrating. Below is the output of 'sudo fdisk -l /dev/sda': Disk /dev/sda: 120.0 GB, 120034123776 bytes 255 heads, 63 sectors/track, 14593 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xd8000000 Device Boot Start End Blocks Id System /dev/sda1 * 14267 14594 2620416 c W95 FAT32 (LBA) /dev/sda2 10 1315 10485760 7 HPFS/NTFS /dev/sda3 * 1315 6276 39852216+ 7 HPFS/NTFS /dev/sda4 6277 14594 66807327+ f W95 Ext'd (LBA) /dev/sda5 14267 14594 2620416 dd Unknown /dev/sda6 6277 13935 61520886 83 Linux /dev/sda7 13936 14266 2658726 82 Linux swap / Solaris Partition table entries are not in disk order --And here is the output of 'sudo sfdisk -l /dev/sda': Disk /dev/sda: 14593 cylinders, 255 heads, 63 sectors/track Warning: extended partition does not start at a cylinder boundary.
