I've (XP Home, SP3) used PM 8.0 for several years, ever since it first appeared.
FWIW: There is nothing guaranteed about any event...when dealing with a sophisticated computer system, the operating system, or hardware/software employed.
There are persons/users who have boot problems with XP...when attempting to install it, dual-boot, repair, etc.
Sometimes things go wrong, more often they go right.
If a person used PM 8.0 and his/her boot files became damaged/corrupted...it may have been due to the program. But files of all sorts (Windows, programs, data) become corrupted/damaged every day...we cannot say definitively what causes this damage.
