I used a Windows 7 ISO that I made from a slipstreamed Windows 7 DVD installer that I made a few years ago.

ignatzatsonic I got here googling and I know this thread is a little old but could you please explain me how did you made that DVD? Thanks in advance.

To install in UEFI you must have a UEFI BIOS. Sandy Bridge (i5 2450m) use to have Legacy - MBR BIOS.

My HP Pavilion g4-2082la laptop has BIOS and UEFI. It came with W7 64bit Home Premium preinstalled in BIOS mode. I upgraded to Windows 8.1 64bit in UEFI mode without problems, which is the maximum it supports. But it runs slower and hotter than W7. So I came back to W7 (simply switch disks) and began this insidious process of installing W7 in UEFI mode. Why? Because sometimes I need to connect discs that are more than 2TB in size. Thanks for your tutorial, I'll try it.

The tutorial is to add USB 3.x and new SATA drivers to the win 7 installation disk. I think you don't need it.
To install as UEFI - GPT, insert the Win 7 64 installation disk and launch boot menu. Choose to boot as UEFI. Go to install - Advanced - delete ALL partitions - create new.
It will create 3 partitions
- 100M - Fat32 - UEFI
- 120M - RAW - MS reserved
- Big NTFS
Install on big NTFS

Its exactly what I do. I tried to install with DVD and with USB configured with Rufus + UEFI-GPT but it always hangs at "Starting Windows". I dont know what more to do.

Did you create the installers yourself ?

Maybe you just need a fresh Iso file :)

Hello AddRAM. The official unmodified ISO downloaded from Microsoft I used is the same with which I installed W7 in BIOS mode without problems.

Is secure boot and or fast boot disabled?

Why don't you install as Legacy - MBR?
On your laptop there is no performance difference.
