In Topic: Linux and Windows UEFI boot using Tianocore DUET firmware

02 December 2011 - 02:47 AM

Ok, so to follow up on my post and maybe provide some information for the people who are like me and don't understand the in depth details of this project.

I have successfully installed windows 7 in two configurations. Both were completely fresh installs. I followed the guide posted by srs5694, and after that was done I had to replace one file. Explained below. After that, everything seems to work.

Using the Efildr20 from EDK_UEFI64. Your HDD must be IDE or in IDE mode for this to work. I put the windows install files on a 16GB flash drive because for some reason the CD/DVD drive is not recognized at all. Windows does take a little longer than normal to boot, I almost thought it froze at first. I read somewhere, I think from the wiki that is posted on the GIT website that this is known and is expected to be fixed in the future. Performance once inside windows was alright. I will be honest, it felt slower than it should have. Every now and then menus and windows would hang for a split second. Not sure if this is because my drives are in IDE mode, if this is because of using boot duet, or if it is part my imagination.

Edit: When I say for this to work, I mean for the UEFI environment to see your HDD and boot into windows. Assuming you have a working Efildr file, the Uefi environment will work in either AHCI or IDE mode.

Second (with SATA)
Unfortunately when using files from the newest version, the Efildr20 file that is in UDK_X64 hangs for me at "Welcome to UEFI," but as mentioned in a previous post the older version works. Use the version from the commit that starts with 55c55d.... Just replace the Efildr20 that is in your ESP/EFI/200MB (or whatever you named it) partition with the older one. After that I re-enabled AHCI. I had to re-install windows after this because I was getting BSOD. Still used the flash drive to install. Windows boots quite a bit faster this way and the performance in windows is better however still seems slow every now and then.

I could not get Efildr20_FSVariable to work with windows. I don't know the difference between the two so I am not really worried about it...

@srs5694 Your guide was very helpful in getting me setup. However the folder names are a little outdated now. It would be nice if you could update the site again. Or at very least maybe edit in there saying that there may be an issue with Efildr20 and what to do to get that working.

I do realize that it has been a short while since anybody has posted in thread,so maybe it is dead, but hopefully this basic knowledge I put here will assist others as they glance over when looking for solutions.

Once again I appreciate all the help and information provided in this forum. I posted all this because I felt like the information was scattered between this thread and the Git website. Everything that I mentioned here was relevant to me in order to get the UEFI environment and windows running.

I have read this entire thread and have found it very educational, and I admit, I don't understand most of the in depth details explained. A huge thanks to everyone that has made this as simple as it is.

Now, to get to the main reason why I am posting.
I am using BIOS_to_UEFI by following one of the guides provided by srs5694. I can get into the menu when using Efildr20 from the EDK_UEFI64 folder. I can also get to the menu if I rename Efildr20_FSVariable (from the UDK_X64) to Efildr20 . However, the original Efildr20 that is provided in UDK_X64 freezes at "Welcome to UEFI World."

I prefer to use SATA, so I would like to use the Efildr20 from UDK_X64. What is the difference between the FSVVariable and the normal Efildr20? I noticed it was mentioned earlier in the thread but did not understand the the difference between the two.

I have everything installed on my HDD. I used PartedMagic to create the partition tables and reformat the drive. I am using GPT on my HD, which was originally MBR. It has one 300MB Fat32 partition to put Efildr20 and EFI folder into. The rest of the space is not partition. I did not convert the drive or anything, everything should have been wiped clean and started the tutorial completely blank.

My computer specs.
Asus laptop G50V-X1.

Processor: Intel Centrino2 P8400 Dual Core 2.26 GHz
RAM: 4GB DDR 800Mhz
BIOS Version: 213

BIOS Settings (That seem relevant):
Intel Virtualization: Enabled
Intel VT-d: Disbaled
IDE Config (SATA/PATA): Enhanced(AKA AHCI)
