I have just acquired a Dell Inspiron 7720 with Windows 8 pre installed. I want to remove Windows 8 and install Windows 7 in it. Windows 8 is installed in the C: partition which is in GPT style. There are 2 other partitions that seem to be related to Recovery. I don't care about the data in C: but I don't want to lose what's in Recovery. All partitions are in the same physical disk, which has 1TB of total space.
What I tried to do was to go into BIOS, change boot from UEFI to Legacy and boot from my Windows 7 DVD. The installation process then complained that Windows 7 could not be installed in C: because it is a GPT partition.
In my google searches I learned that Windows 7 can be installed in a GPT partition if I enable UEFI in the BIOS and then boot from the Windows 7 DVD in UEFI mode. However, I have no idea how to boot from the Windows 7 DVD in UEFI mode.
Can anybody advise me on how do acomplish this?
P.S.: I did a search here in superuser before asking, but all I found was a thread teaching how to get to the bios configuration screen. I am able to do that, my problem lies elsewhere.
