Dual-boot Vista SP1 and Linux

There are rumors that Vista SP1 does not like other people's boot loaders (LiLo, grub) and refuses to boot from under them. Because of this, my friend even refused to install Fedora Linux on a laptop with Vista Home Premium SP1 installed. As it is written on the Microsoft website, this BitLocker is embedded only in Ultimate and Enterprise branches, so that users of Home Basic, Premium, etc. nothing to worry about. And for the lucky owners of Ultimate / Enterprise - do not worry, everything is much simpler than you think.

Suppose you have Vista Ultimate and Linux (no matter which distro and bootloader, and of course, the dual-boot is installed) and you want to put SP1 on whist. Before installing SP1, you need to restore the Windows bootloader (in the MBR) - insert the disk with Vista, load the recovery recovery console and restore the MBR. Next, we load the whist, install the long-awaited SP1, reboot - everything works. Now you need to disable BitLocker - Control Panel - Security - BitLocker disc encryption. Click Turn Off and remove the check mark. Finally, load any Linux Live CD and restore GRUB / LILO to its original position (in the MBR). Vista will not swear.

If you have Ultimate SP1 and you want to install Linux next to it, then simply disable BitLocker before installing. Everything goes smoothly.

I tried on 2 machines Intel, Vista Ultimate, Fedora Linux 10, grub. On one it was necessary to register chain-loading in grub, for HD is crookedly marked. In general, everything works.

UPD. A good manager to manage bootloaders: EasyBCD is award-winning and compatible with Vista (and BitLocker), and not some sort of fucking Paragon Boot Manager (the link removed some objections ... google will show;)

UPD. Who does everything so work, enable BitLocker and stop complaining ...
