now mind you, I am in windows, i hit restart, then hit del, tell the bios to boot from USB, and then save and exit. When it goes to boot from the USB i get an error
BOOTMGR IS MISSING
CTR+ALT+DEL to restart
tried 3 or 4 times, same error almost instant, go back into bios, change back to my HD as primary boot device, and then can get right back into windows error free.
So, i believe I may have did something wrong with creating the USB drive? Should there be a bootMGR on the usb thumb drive? Ultimately what I want, is when i boot up my PC it give me the option to boot into XP/7/10.

The configuration data that BOOTMGR requires can be found in the Boot Configuration Data (BCD) store, which is a registry-like database. The database replaces the boot.ini file used in old Windows versions like Windows XP.
The BOOTMGR file itself is both read-only and hidden, which is located in the root directory of the partition. It is marked as “Active” in Disk Management. In most Windows PCs, this partition is labelled as “System Reserved” without hard drive letter.
If there’s no the “System Reserved” partition, probably the BOOTMGR is located on the primary hard drive (in most cases it’s C drive). The boot manager will execute winload.exe, which is the system loader that is used to continue the Windows boot process.
