Cannot boot to original OS from HDD

After creating the boot USB with Porteus I might have carelessly applied Porteus Installer for Windows on the actual HDD with Win 7 OS.
So when I want to boot from HDD I get syslinux message 'SYSLINUX 4.06 EDD ...' with 'boot failure : No DEFAULT or UI configuration directive found!' and prompt starting with 'boot: '.
Is it possible to do something to revert this and restore it back to windows boot loader?
Thanks

Regarding url tag ... dunno. Something weird indeed. URL's under 55 characters don't need the url tag. It prevents the magic shortening of a URL but for some reason doesn't work on this short url. I removed the tag and the link works. Will look into why it didnt with the url tag. Thanks.

I think I recall this problem on a link awhile back, the solution was to remove the "/" at the end of the URL The URL works fine with or without the "/" at the end but the url tags function doesn't like it.

maybe you need only set bootable flag on proper partition e.g. sda3
eventually connect your pendrive and modify syslinux (add grub legacy) and set for grub's menu.lst these lines
Code: Select all
title BOOTMGR of Windows VISTA/WIN7/WIN2008
find --set-root --ignore-floppies /bootmgr
chainloader /bootmgr

On Linux open terminal as root or switch to root (su command) and execute
or set boot flag via fdisk, cfdisk or graphical gparted.
On Windows there are somewhere Administrative Tools and submenu Disks (I don't remember name) - here you can set active flag on chosen partition.
