So I'm using Ubuntu live CD to install Ubuntu next to Windows 7 but it doesn't recognize partitions. Here is sudo fdisk -l: Disk /dev/sda: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0c7a859b Device Boot Start End Blocks Id System /dev/sda1 63 1250259631 625129784+ f W95 Ext'd (LBA) Partition 1 does not start on physical sector boundary. /dev/sda2 * 81920 4177919 2048000 b W95 FAT32 /dev/sda3 4177920 147535871 71678976 7 HPFS/NTFS/exFAT /dev/sda5 147538608 1147859631 500160512 7 HPFS/NTFS/exFAT I have one partition with Windows 7, one with its created partition (OS) and one for data.
