Installing Windows 10 on a GPT disk with legacy BIOS and GRUB2

In my first entry in this blog, when I set up the hard disk partitions it was ready to install Windows. However, since then I had not returned to deal with this issue and now is the time to take it up.

Since Windows 8, the Windows installer is able to install Windows on GPT partitioned disks, as long as the computer supports the UEFI mode.

In this post I intend to show a method to work around this limitation of Windows installer. I'll install Windows 10 on a computer with a traditional BIOS and the hard disk partitions with GPT style.

Install GRUB2 on GPT disk with dedicated partition

When you plan to setting up an x86 computer from scratch, should be considered the following issues:

  • Whats the computer role?
  • it support  UEFI BIOS?
  • Will be dedicated to a single operating system, or is intended to host multiple OSs?
  • Which bootloader is intended to install?.
  • How to allocate disk space?.

In my last laptop for testing, I configured  a GPT partitioned disk with homogeneous partitions sizes and then have installed GRUB2 as independent  bootloader. This configuration allows me great flexibility in allocating storage space and isolates the different S.Os installed.

The choice of GRUB2 is almost obvious, is the default bootloader for a lot of Linux distributions. It  reads  most  file systems, it can boot directly almost all OSs, or  chainloading with another bootloader to boot the OS -the last is my preferred option-.
 
Next, we will review the implementation process I have done.
