How can i unistall de Bootmanager BootStar (Shareware version).
My Hd had been formated and i updated de bios. But the red window of the bootmanager continues appearing. Where is the program installed ? Thats my doubt. Thanx.. :)

Powerquest's Boot Magic installs itself into the master boot record and I expect that most, if not all, such programs do the same. It's the obvious place. Since the MBR is invisible to (most) operating systems and unaffected by the FORMAT command you will have some trouble putting it right. I assume you uninstalled Bootstar in an orderly manner or was that not an option? If you simply deleted files then reinstall it and try to uninstall properly. Everything else I can think of will not only remove Bootstar but all your data as well. If this is acceptable then try the following bit of machine code. You will need a bootable DOS floppy with DEBUG, FDISK and FORMAT on it.

DEBUG (ENTER)
;ONCE YOU SEE THE DEBUG DASH PROMPT (-) TYPE IN THE FOLLOWING:

A (ENTER)
;DEBUG WILL NOW OUTPUT A SERIES OF LETTERS AND NUMBERS. NOW ENTER:
MOV AX,330 (ENTER)
MOV CX,1 (ENTER)
MOV DX,80 (ENTER)
MOV BX,3800 (ENTER)
MOV ES,BX (ENTER)
INT 13 (ENTER)
INT 3 (ENTER)
(ENTER)
G (ENTER)
Q (ENTER)

YOU SHOULD NOW BE BACK AT AN A: PROMPT.

YOU WILL NEED TO REBOOT, RUN FDISK AND FORMAT.

This will wipe your MBR clean. I've tried it and it works but I would remove any other hard disks from your PC first.

no need to write extra codes. only boot your pc from cd rom and give this command on dos prompt.
fdisk/mbr
this will restore your master boot record.
