How to make NT boot drive?

Hope so this is not somewhere around in knowledgebase and someone find it useful... You can create boot drive to boot into Windows (tested on w2k and xp). This is specially useful, if U need to use your own boot.ini option (for debugging BSOD for example).

Only thing U need to do is to copy this threee files to EMPTY formatted medium:

ntldr

ntdetect.com

boot.ini

U MUST copy the ntldr first! Then copy the rest of the files.

And thats it! Simple and (for me) quite useful... The final boot medium is compatible with older OS, so boot medium from XP SP2 can be used to boot to w2k with no problems.

If anyone can speak czech/slovak, you can find whole article in www.supersupport.org under boot.ini

That only helps though if you set the BIOS to boot to that drive, and only if the drive is formatted to NTFS... If its for a cd, or floppy, even if it is formated to IBM, or CDFS standards, it wont work... Also, the NTLDR file is purly for booting the ntoskrnl file. Also, it depends on what your BIOS is, sometimes it will tell windows that the EIDE/SATA/SCSI orders are different depending on the boot partition...

Still, it is a cool way to test different installed systems, and for recovering from corrupted installs...

Hmm, interesting, maybe i was just doing it wrong whenever i tried it... I know that it will work providing that you are running an NTFS(possibly fat32, i cant remember how that boots) machine and that as long as you havent changed any hardware it will work, but as far as i understnad, if you arent it wont work...

Still, you may be right, i dont do this often, i might have been doing something wrong... go figure...

soulin,

yes it's a known fact.

There is even this program BOOTPART

(which you might have skipped in this thread):

http://www.msfn.org/board/index.php?showtopic=35280

that does what is missing, i.e. recreates the boot sectors.

See here for more info:

if you run a SCSI machine you need a fourth file, ntbootd.sys!

mattofak,

to clear up things:

NTLDR from NT4.00 can boot only from FAT16 and NTFS partitions

NTLDR from Win2k, XP or 2003 can boot from FAT16, FAT32 and NTFS partitions

Unless you have a third-party bootmanager, this refers to FIRST ACTIVE PRIMARY partition on FIRST hard disk.
