Talk:Boot disk

Other system types
I know that in Mac OS X, it is possible to boot from the OS X install disc by holding down the "c" key as the system boots. This is done to reinstall, or to change basic system settings (e.g., resetting the administrator's pw). This is about all I know, though, so someone with more knowledge should edit this. Is the procedure the same for older versions of the OS? Are there any, or many, other bootable disks available for Apple machines? L Glidewell 00:16, 26 May 2007 (UTC)

boot sector required
are there some requirements of the bootable sector? I wrote a boot sector based on a bootable usb disk which does boot the PC. After I update the disk boot sector, it does not boot the PC, just like nothing is there. Nevertheless, my boot sector can boot the PC from other usb disks. How could explain this?

 * Some flash drives identify themselfes as USB hard disks (or as IDE or SCSI HDDs when legacy mode is enabled and the operating system isn't USB aware), so they use an MBR, floppies (and USB-sticks identifying themselves as removable media) use a VBR, which is not compatible with MBR. --MrBurns (talk) 14:07, 30 June 2012 (UTC)
