Tried to up grade Toshiba Laptop, from Windows XP to Windows Vista Business, Laptop won't install updates and now NTLDR error message comes on screen at start up.
Can I download free NTLDR from Toshiba or other resource?

NTLDR is the boot loader. It's absolutely needed to boot from any NTFS formated drive. It's a CORE Windows component.
It's NOT offered as a freestanding file.

You probably need to reinstall/repair the OS, or update to 7, to fix that problem. You may try to boot from the install DVD and chose the REPAIR or UPDATE option when offered.
I suggest that you go for Windows 7 instead of Vista. It's faster, use LESS resources than Vista, have many bug fixed,... The installation from Vista is SAFE for your data.
