If you have an old hard drive installed windows XP, no partitions, and old system is broken (the old CPU,MoBo,GPU,PSU,RAM). But you are planning to buy the new system and using the old hard drive,could you just run it in safe mode and install the drivers of new parts and uninstall the older ones?-one asked
Generally, it should boot just fine, unless you are changng your class of CPU (different socket, different amount of cores etc) in which case you will get a BSOD on boot, in which case you will have to do a repair install. Either way you will probably have to re-activate windows (due to new mobo).
Tip: Set your BIOS in the new computer to put its SATA/IDE ports in emulation (or IDE) mode. Don’t use AHCI or RAID. This will make the new computer look more like the old one and increase the chances that it will boot.
