Help please, endless loop while installing windows 7

[cowlquape]

I was trying to install the windows 7 beta on my t61, however something must have gone wrong an now it is in an endless loop of restarting, saying that the instalation failed, and that it will undo the instalation. However as i said this clearly is not happening, what should i do so that i can at least get vista back onto my laptop.

So, i finnaly found my manual, and it isn't helping,

it says to press the thinkvantage button to interupt the startup and that the rescue and recovery workspace opens, but it doesn't. i get the startup interupt menu with a choice of entering bios setup utility, or choosing a temporary start up device, or starting normaly and going back into the loop. What do i do since my computer didn't come with a vista disk.

Do you have any restore media? I would try restoring your system then try the install again. If you don't, it sounds like the R&R partition is already destroyed by the Windows 7 install and you will need to call Lenovo Tech Support to obtain restore disks.

yeah, that seems to be the only solution that could work.
