Solved: grub error 18; Selected cylinder exceeds maximum supported by BIOS Discussion in 'Linux and Unix' started by jrbuergel, Aug 2, 2011. Thread Status: Not open for further replies. Advertisement jrbuergel Jim Thread Starter Joined: Jan 17, 2004 Messages: 772 The internal Linux and XP do boot fine, but all 5 Linux installed on the external sata drive do not boot, but give grub error 18; "Selected cylinder exceeds maximum supported by BIOS", but the partitions do look okay when viewed from either a windows XP Linux file system tool, or from booted into one of my internal drive Linux http://www.supergrubdisk.org/forum/index.php?topic=150.0 and from that newer disk utility, such as in Fedora 13 or 14. After more google searching I did find out that this issue is caused by a limitation in older motherboards BIOS, which my computer is fairly old as a 5-06 Gateway. This limit is that older BIOS will only search for boot files in the first part of the drive. So the solution is either to flash a update into the BIOS, or create a separate https://forums.techguy.org/threads/solved-grub-error-18-selected-cylinder-exceeds-maximum-supported-by-bios.1010466/ boot partition near the beginning of the hard drive. The weird thing is that all my external drive Linux have been booting up just fine for quite some time now. jrbuergel, Aug 2, 2011 #1 Sponsor saikee Joined: Jun 11, 2004 Messages: 3,782 This error has one cure if your 5 Linux are store at the end of a 2TB external hard disk where Grub1 would not be able to access and the cure is to use Grub2. If this isn't your case read on. However Grub1 has a bug and it is quite common to see this error if you use a Grub1 version newer than the one in the internal hard disk which always boots first. It occurs if you pass the PC control from an older Grub1 to a newer Grub1. Although Grub1 has stopped maintenance after the 0.97 version many distros doctored it for their own purpose and their work may not be thorough. You could overcome this problem by using the latest Grub1 in the internal hard disk. If you see Grub prompt with v0.97 it would be the original older version. Those have been doctored show up without a version number displayed. saikee, Aug 3, 2011 #2 jrbuergel Jim Thread Starter Joined: Jan 17, 2004 Messages: 772 Okay thanks for that help.

supported by BIOS -------------------------------------------------------------------------------- Hi, I am running Jaunty Jackalope on a new machine and after a recent update I got the following message when trying to https://answers.launchpad.net/ubuntu/+source/grub/+question/93844 reboot: Error 18 - Selected cylinder exceeds maximum supported by BIOS After reading some of the info on Grub error 18 I decided to create a separate boot partition, as suggested. However, when trying to use Gparted from the live CD to create some space ahead of /sda1, Gparted would run for a while and then crash. The crash message says: error 18 "e2fsck crashed with SIGSEGV in qsort" So now I am stuck, unable to boot from HDD and unable to create new partitions (the other partitions on the disk work fine with Gparted). Could all of this be due to corrupt /sda1 partition? Since I am pretty new at this I would appreciate any help. Thanks in advance!
