Guest machine on VirtualBox-4.1 "BOOTMGR is compressed."

[luceliofreitas]

Hi friends,

I updated from Fedora14-x86_64 to Fedora16-x86_64 host, and I thought
VirtualBox-4.0 was ok. When I started Winvista64 Guest I got the message:

BOOTMGR is compressed
Press Ctrl-Alt-Del to restart

I did it, and the Winvista64 boot started again and stoped at the same
point. In a loop.

I thought that the problem was VirtualBox for Fedora14. I removed it.
So I installed Virtualbox-4.1-4.1.6 for Fedora16-x86_64.

The same thing is happening. Why bootmgr has changed? Anybody helps?

The guest machine was working since a long time. I only updated
Fedora14 to Fedora16.

Thanks in advance,

Where are you getting your VirtualBox install from?
Fedora or VirtualBox.org?

I am getting the VirtualBox from Fedora.

Well we don't really support (fully) the distro branches of VirtualBox. They change it to meet their needs but I did fine a possible solution for you.

Problem solved.

I found the solution following the pointer sugested by Perrig (http://www.howtogeek.com/forum/topic/bo ... compressed).

insert your OS CD
go to DOS window and type in your OS driver (usualy C:/
type in bootrec /FixMbr
then type in bootrec /fixboot
then type in bootrec /rebuildbcd
then type in exit
restart your coputer
it will work 100% only if you prompt at the same order

I recovered my WinVista64.

Thanks a lot.
