I have an HP 250 G1 laptop that came loaded with Windows 8. I later installed Windows 7 in Legacy mode. Now I want to go back to Windows 8 in UEFI mode. I just want a clean untouched Windows 8.1 .iso that will preferably use the key already in this laptop. Thing is I had Windows 8 on here before, not 8.1. I don't know if my key can still be used. Can anyone provide a link?
Luckily I wrote down some info before putting Win7 on it. Here's some info I have when I had Win8: MSDM: HPQOEM Product key: (I have it written down) IE key: (I have it written down) And then I went into BIOS with the laptop, and I retrieved this info: Factory installed OS: Win8 System Board CT Number: (I have it written down) Product configuration ID: (I have it written down) UUID Number: (I have it written down) Serial number: (I have it written down) So with this information, what do I have to do now?
