Installation of 64-bit

[bocado]

A friend has a new build, we installed the 32-bit version for him, but he managed to get a 64-bit copy from an accountant/friend.
When trying to install the 64-bit he gets the BOOTMGR error now and the system won't read either the 64bit nor the 32bit version, period.
He tried installing XP on it and nothing still. I remember reading problems occured mainly with SSDs and partitions, but a regular SATA HDD?

Anyone have any suggestions for me before I head over there tomorrow to get his comp., up and running?
Thanks.

Please recap the installation procedure. Where and how did he try to install the 64bit version? Same drive? Separate partition?

Is it legit

Run the repair install from the WIN7 disk, installing XP might have broken everything depending on where you tried to install it to.

XP is not aware of WIN7 and therefore would not know what to do about it.
