UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with

Try UEFI install first so you can benefit from those features, unless it will not install.

To attempt a UEFI install you should use Rufus set as shown in Option One of tutorial to UEFI to GPT. Make sure all the other settings are exactly copied too.

Then boot the stick as a UEFI device using BIOS Boot menu key at boot. If it wouldn't show up before it is likely because it was not formatted correctly in the first place. If Rufus isn't used then it must be manually edited as shown in the other option. But Rufus is what works best and is automated so please do it now.

The UEFI does not recognize the USB if it is formatted in anything other than FAT32 and RUFUS only formats to NTFS and if you change the format settings, it will give an error and then goes back to NTFS.

The only thing that works is that I format it to FAT32 in my other Windows 7 operating system and then paste the contents of a bootable Windows 7 32bit DVD to the USB. The UEFI only detects the USB that way but it does not go beyond that. It only shows in the bootable devices and I cannot override nor boot from it by pressing ESC before the UEFI menu comes up

Did you look at the steps for Option One in UEFI Bootable USB Flash Drive - Create in Windows
which clearly show both in a picture and the settings specified for the stick File System to be FAT32?

Yes but when I give the ISO file to RUFUS, it changes the parameters to NTFS. I downloaded the Windows 7 iso file from the link that was given to me in previous posts here plus I have another two ISO files... all from different sources but everytime I give the ISO, it changes back and when I change the parameters after giving the ISO, it gives an error. Attaching screenshots. Only makes NTFS partitions and always changes back.
Use the Windows 7 USB DVD download tool too and that too converts the file table to NTFS which my UEFI does not recognize

If you look at Partition Scheme it is MBR and not UEFI.

Compare the picture in the tutorial to your picture to make the changes needed.

Tried the third option GPT partition scheme for UEFI too.. but with a different error

I see now what the problem is. You must use 64 bit to install to UEFI, so you'll need to use Legacy for MBR if you're using a 32 bit ISO.

Didn't understand that....

With that processor and only 2gb RAM you'd likely want to stick with 32 bit. That can't be installed to UEFI.

Have you tried writing the 32 bit ISO to stick with Windows 7 USB-DVD Download Tool to see if it shows up?

Yes I did and that utility again formats it to NTFS which does not show up. So you mean to say that nothing can be installed on that?
