Windows Install on GPT for UEFI Arch Linux Dual Boot
0 replies, posted
[Solved]
Hello, I am attempting to install Arch linux and dual boot it with windows. As I am running a modern UEFI system, I have put my SSD (see Specs below) in GPT format (losing my original windows installation in the process) where I plan on installing the UEFI boot loader, Windows, and Arch. At the moment I'm trying to reinstall Windows 7 (Professional x64), so I can do a UEFI boot. When I use Rufus to create a bootable GPT USB drive, I get the boot error 0xc0000225. When I try to do it manually with these ([url]http://www.eightforums.com/tutorials/15458-uefi-bootable-usb-flash-drive-create-windows.html[/url]) instructions, my computer does not recognize my flash drive as bootable (it gives the insert proper boot media error). I am using this ([url]http://msft.digitalrivercontent.net/win/X17-59186.iso[/url]) for the ISO, I also have an old installation disc. Booting the ISO without modification in Legacy BIOS works just fine, but I have no way to install windows to a GPT drive while booting in Legacy BIOS (Windows states it cannot be installed to a GPT drive, probably because it detects the system is running legacy bios instead of UEFI). Any help you can provide is appreciated.
Specifications:
CPU: i5-4670k
Motherboard: Z87x-D3H Gigabyte
SSD: OCZ Vertex 3 (Set in GPT mode)
HDD: Western Digital Caviar Blue
Flash Drive: 8GB JetFlash Transcend USB 3.0
Solution:
Put Rufus into MBR for UEFI system mode with FAT32 partition. This will partition the flash drive as MBR with a single FAT32 partition which contains the installation files for UEFI booting. Make sure the only drives connected are the drive to install windows too, and the drive containing setup files. I had an issue where my HDD which contained a copy of the original windows partition was being recognized as a valid windows boot drive causing the 0xc0000225 boot error.
