Again, fdisk is your friend: [root at centos ~]# fdisk /dev/sda The number of cylinders for this disk is set to 2231. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): l 0 Empty 1e Hidden W95 FAT1 75 PC/IX be Solaris boot 1 FAT12 24 NEC DOS 80 Old Minix bf Solaris 2 XENIX root 39 Plan 9 81 Minix / old Lin c1 DRDOS/ sec (FAT- 3 XENIX usr 3c PartitionMagic 82 Linux swap c4 DRDOS/ sec (FAT- 4 FAT16 <32M 40 Venix 80286 83 Linux c6 DRDOS/ sec (FAT- 5 Extended 41 PPC PReP Boot 84 OS/2 hidden C: c7 Syrinx 6 FAT16 42 SFS 85 Linux extended da Non-FS data 7 HPFS/NTFS 4d QNX4.x 86 NTFS volume set db CP/M / CTOS / . 8 AIX 4e QNX4.x 2nd part 87 NTFS volume set de Dell Utility 9 AIX bootable 4f QNX4.x 3rd part 8e Linux LVM df BootIt a OS/2 Boot Manag 50 OnTrack DM 93 Amoeba e1 DOS access b W95 FAT32 51 OnTrack DM6 Aux 94 Amoeba BBT e3 DOS R/O c W95 FAT32 (LBA) 52 CP/M 9f BSD/OS e4 SpeedStor e W95 FAT16 (LBA) 53 OnTrack DM6 Aux a0 IBM Thinkpad hi eb BeOS fs f W95 Ext'd (LBA) 54 OnTrackDM6 a5 FreeBSD ee EFI GPT 10 OPUS 55 EZ-Drive a6 OpenBSD ef EFI (FAT-12/16/ 11 Hidden FAT12 56 Golden Bow a7 NeXTSTEP f0 Linux/ PA-RISC b 12 Compaq diagnost 5c Priam Edisk a8 Darwin UFS f1 SpeedStor 14 Hidden FAT16 <3 61 SpeedStor a9 NetBSD f4 SpeedStor 16 Hidden FAT16 63 GNU HURD or Sys ab Darwin boot f2 DOS secondary 17 Hidden HPFS/NTF 64 Novell Netware b7 BSDI fs fd Linux raid auto 18 AST SmartSleep 65 Novell Netware b8 BSDI swap fe LANstep 1b Hidden W95 FAT3 70 DiskSecure Mult bb Boot Wizard hid ff BBT 1c Hidden W95 FAT3 Alfred
