Checking the Existence of UEFI Boot in Your System

Switch off your Dell PC, then switch it on. When the system starts, press and hold the f12 key. You’ll be directed to the boot menu.

If the boot menu mentions the ‘boot option’ at the top, it indicates you have a UEFI boot.

If you want to install Windows 7 64-bit OS on your Dell PC, follow these steps:

  • Set the boot mode to UEFI.
  • Turn off the secure boot option.
  • Enable the legacy ROM settings.
  • Early UEFI systems might not have Secure Boot, so there is no need for Legacy ROM settings.

On the other hand, if you want to install Windows 7 32-bit Pro, follow these steps:

  • Set the boot mode to legacy.
  • Turn off the secure boot.
  • Turn off the legacy bott settings.

Creating Bootable USB Flash Drive

Reopen the Rufus and launch the installation.iso. insert a 16 GB USB flash drive. Your USB device will be displayed under the device option.

The Partition Scheme for Windows 7 64-Bit

If you install Windows 7 64-bit for the first time, it will default to the GPT partition scheme. GPRT has numerous advantages. For instance, it contains multiple boot records rather than single ones, supports many partitions, and can work with larger devices. 

Eventually, the target system, file system, and cluster size will update automatically.

We strongly recommend you change the partition scheme from FAT32  to NTFS. NTFS can transfer files of any size, whereas FAT32 can transfer only 4GB files if you follow my instructions to install Windows 7 pro or dell, the install.win will be greater than 4 GB. For this reason, the NTFS partition scheme is mandatory in this case.
