Answer 2

The problem is that the boot is altered.

First try booting in safe mode with F8 (only has me once)

If this fails, usually work doing home repairs

If not will (need to know if installing EFI or BIOS) recharge the boot files on the system particióbn (bcdboot). This should not fail (console and load must first identify the letters of volume)
