Will do - planning on a full clean install using Kari's tutorial. Going to partition out the 2TB Seagate for media/backups. Not quite sure what to do with the existing SATA II SSD and platter drives, but I'm sure I'll figure something out!

Windows 7 Professional 64bit
 
 

Hi everyone,

Thanks for providing the tutorial, I made my way here through google .
I bought new hardware some months ago and finally wanted to get everything running the way it was intended to run from the beginning (triple boot using Win8, Windows 7 and CentOS).

I own MSDNAA/Dreamspark copies of Windows 7 Professional 64bit and Windows 8 "N" and have been trying to get my Windows 7 UEFI install up and running since yesterday. It's really starting to drive me crazy, because I simply never get to complete the installation.

Some further detail about my Hardware:
Xeon E3-1230v2
asrock H77 Pro4/MVP
Seagate 3TB disk

I can access the "UEFI" boot mode for the DVD-drive through my boot menu, so it is indeed starting in EFI mode.
During my first run I kept all UEFI settings default (secure boot disabled, "boot mode" was set to "setup"). The disk was pre-initialized with a GPT (using gparted) and during the partitioning process of the Windows 7 installation procedure I was able to create 3 partitions, however, a warning displayed as also mentioned in the tutorial ("Windows cannot be installed to this disk. This computer's hardware may not support booting from this disk. Ensure that the disk's controller is enabled in the computer's BIOS.").
I disregarded the message and hit next, the installation then proceeds until right after the updates are installed, rebooting thereafter.

Whatsoever, the installation process does not continue from there on. In the UEFI boot menu it shows "Windows Boot Manager" as top priority and if firing that up I get an "unexpected error" (Status 0xc0000225) - it says that due to recent hardware or softwarechanges windows might not be bootable.

I reiterated several times, using diskpart instead of gparted, setting secure boot to enabled (thereby changing the "boot mode" to user), resetting it to disabled and so on and so forth - without any success.

I would be really glad if someone could help me out - has anyone gotten Windows 7 to run on that particular board? I figure the Z77 series should do as well (someone over here seems to have gotten it running).

Thanks a lot in advance for any advice.

Windows 7 Home Premium 64Bit
 
 

Hi all;
Just wanna ask for some advice. I am about to "downgrade" my Lenovo Y580 from Win8 to Windows 7 Home Premium (64 bits). Obviously, the Lenovo Y580 comes pre-installed with Win8 and UEFI enabled. After researching via Google, apparently, Windows 7 can be installed on both BIOS and UEFI. However, UEFI seems to be very complicated / daunting to me. I am just an average everyday computer user. Hence, does going the extra mile to install Windows 7 on UEFI brings any considerable benefits?

Also, in terms of doing a cold boot, which is faster? Win 7 on UEFI or on BIOS? Or the difference is just a few seconds and it is negligible?

Watch this video to understand the difference better between UEFI BIOS vs. Legacy BIOS - YouTube.

If you want to try then follow these steps for UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

If its more trouble than its worth for you then you can Bypass UEFI to Install WIn7.

Either way with a Win8 PC you'll need to disable Secure Boot in BIOS setup as shown in Downgrade Windows 8 to Windows 7

Interesting YouTube video but it doesn't convince me to change. I thought the comment that went along the lines the old BIOS code was written in assembly language while the new was written in C a bit amusing. What do you think any high level language gets turned into (CPU instruction set). If anything this makes it easier for hackers to play around with your BIOS boot code.

I see no real improvement with UEFI or Secure Boot which just upend all of the install and repair regimens we mostly developed here since beta. But I'm also wary to wholesale advise users to Bypass UEFI to Install Windows 7 since the Best Practice isn't certain yet. It also caused Saltgrass who has the edge on UEFI help knowledge to storm out when I suggested BIOS/MBR installs too much. That is still a sore spot with me I feel guilty about.

Some users do brag about much faster boots and for some reason like the UEFI GUI which is useful how exactly?

My motherboard is UEFI BIOS and the GUI is definitely far better. However, I still do an MBR boot.
I must admit it was so long ago that I did the clean install I cannot remember how I chose MBR over UEFI for booting. Does it come up as an option or does it depend on whether your HDD is GPT formatted? What happens when installing to an unallocated drive with a UEFI BIOS. My memory must be going!

That is the appeal of UEFI , it looks better. Is it more functional, no..well you can use your mouse, and view it from within windows.
