Updating bios windows xp
Don’t be put-off by the title though, these same steps apply to any legacy NT-based operating system, meaning that these same steps are used (without exception) to boot into Windows 2003, XP, 2000, Neptune, and NT.This article refers to the technical aspects of the Windows XP bootloader and provides background information needed to fully understand how to correctly dual-boot newer versions of Windows (including Vista, 7, and 8) with Windows XP.NTLDR can’t get its list of operating systems from anything other than the on the active partition on disk 0, so if you add another operating system to the mix, you end up with something like this: Basically, you have to go through a two-level boot menu, and you cannot – however hard you try – add both Windows XP entries to the main bootmgr boot menu. We’ve developed our own version of NTLDR, and bootmgr will load a separate copy of Easy LDR for each Windows XP entry in the menu.In order to load either of the two XP entries, you’ll need to select the NTLDR entry (called “Legacy Entries” by default) from the bootmgr/bcd boot menu, and select the copy of Windows XP you wish to boot into from the second menu presented by NTLDR. Each copy of Easy LDR is configured to boot into one and only one copy of Windows XP, so your complicated two-level boot menu in the previous picture boils down to a much simpler and prettier result: Keep in mind that since there’s only one entry in each Easy LDR instance, no second menu will ever appear.Creating a new Windows XP entry with Easy BCD is very easy.By default, Easy BCD will create a Windows XP entry via the NTLDR method described above in order to minimize confusion and because most users will not have multiple legacy entries alongside their Vista/7 installs.Just enter a name for the new entry that will appear in the boot menu, and click “Add Entry” and Easy BCD will automatically create the needed boot files.NTLDR will be placed in the NST subfolder as shown above, and NTDETECT will be placed in the root of the boot partition.
COM and the ebcd.00x files will still be placed on the unmounted boot partition.
The reason for either of these annoying interruptions is that the driver for your hard disk simply isn’t on the Windows XP CD….bummer eh.
