I have been given a Compaq Presario desktop running Vista Home Edition. I would like to install a newer O/S, Win10 ideally but 7 or 8.2 would do. The problem I have is that I cannot get it to boot from the DVD drive even though I have set it in BIOS.
Trying to install from within Vista it asks me to put a disk in the drive which I have but it ejects it. Any games or audio disk is seen OK.
I have a Microsoft printed Retail edition of W8.2 also a Win7 disk that I bought, also printed which has worked before and a Win10 iso that I have used on 2 other PCs. It just wont boot from any of them, the flashing cursor appears at the top left and it would normally ask me to press any key to boot from the CD but it does not, it just keeps flashing until it defaults to Vista.
The Windows 10 iso is presumably an upgrade. That will not work with Vista, because Vista installations were not included in the Microsoft free upgrade offer. although you can install Windows 10 if you buy a copy.
