[SOLVED]bootmgr is missing (tri-boot with Lion, win7,ubuntu)

[dem3trio]

Hi everybody,

I've just installed and configured Lion, and when i try to access the GRUB to load kubuntu or Win7 i get the message "Bootmgr" is missing. I can only run win7 with the system reserved partition, but I cant boot linux.

This is what I have:
HD1 250GB - GUID - All with LION and a little partition for Time Machine
HD2 1TB - MBR - With Win7, Ubuntu and a Huge Partition for data sharing between OS.

This is what i did:

I couldn't format the MBR Hard Disk to a GUID, because i didn't have enough space on any other hd to backup all the info, so i had to use those partitions to install (first) Win7 and then Ubuntu.

When everything was installed i set to Slave that HD and I installed Lion on the 250GB as a Master HD.

Is there any way to get access to the grub bootloader for boot into ubuntu?

thx in advance!

Win7 boot files are located in the System reserved partition, so that is the partition to select from Chimera boot loader on the OS X boot drive to boot Win7.

For Ubuntu, you must install Grub2 to the root of the Ubuntu partition ( / ) in order for Chimera to see it. Or, you can create a boot partition (/boot) and install Grub2 there and Chimera will see it.

When I get to the Chimera screen, all I see is Lion and Windows. When I choose Windows I get the "bootmgr is missing press ctrl+alt+del to restart" message. I don't see the system reserved partition in Chimera. I can only see it in the BIOS.

Is there a way to see it and boot from Chimera?
