Got an HP desktop that came out of the factory running Win7. The owners did the Win10 upgrade, and then they got a severe malware attack. After getting rid of that, Windows wouldn’t work, and neither would a Repair Install. So last night I did a full install. The “pre-install” partitioning was a small System partition, an OS partition, and an HP Recovery partition. The Windows10 install wouldn’t go forward because the System partition had no free space, so I formatted it to remove its contents and then did the Win10 install in the OS partition. Now there is the empty old System partition, the OS partition, an unnamed partition showing as Recovery Partition in Disk Management, and the original HP Recovery partition.
Is there any reason I can’t (or shouldn’t) remove the old System partition and the HP Recovery one, and add the space to the OS partition? And is the Win10 Disk Management program OK to do this with?
