Installing Windows 7 in UEFI Issues Detecting Other SATA Devices

Q: Installing Windows 7 in UEFI Issues Detecting Other SATA Devices

I have an ASUS ROG RAIDR Express PCIE SSD which I have it in UEFI mode where I was able to install Windows 7 successfully on it with my motherboard BIOS set to UEFI mode and CSM to UFEI as well. But now when I connect my storage HDD's and my 2 Corsair Neutron GTX SSD's which I set up in a RAID0 array in Legacy mode along with my Blu-ray RW optical drive, they're not recognized in Windows at all. How can I get Windows to recognize my drives in UEFI if even possible at all? I've tried switching the CSM back to Legacy to see if that'll work, but my system gets stuck in boot loop after the Intel RAID setup screen.

Preferred Solution: Installing Windows 7 in UEFI Issues Detecting Other SATA Devices

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


I just installed Windows 8.1 and it works, but the installation was very difficult. I'm hoping someone can help me understand what happened so that future installations go more smoothly.

I was running Windows 7 on a custom desktop PC with an Intel motherboard (~3 years old). I downloaded Windows 8.1 and burned the installation W8.1 DVD. I rebooted to the installation DVD. My PC has 3 hard drives, 2 are blank, the other partially occupied by a W7 installation. I installed W8.1 onto the remaining space on the third drive. The installation seemed to work. W8.1 booted from the hard drive after rebooting from the DVD. However, after I removed the DVD and rebooted the PC it booted to W7: no choices, no bootloader, etc. If I reinserted the installation DVD and booted the DVD, it would boot W8.1 from the hard drive. Weird.

Question 1: why would W7 boot when the W8.1 installation DVD is not inserted, where W8.1 would boot from the hard drive after booting from the DVD?

Next: I found no solution. W8.1 would not let me burn a recovery DVD. The installation DVD presented no options for recovery, repair, etc upon boot, it would just boot W8.1 from the hard drive. So, thinking that MBR was clearly set to boot W7, I decided to wipe the drive by installing Linux. I then inserted the W8.1 installation DVD, hoping to install W8.1 over Linux, but got the message "A resource is missing". I spent an hour on the phone with Microsoft, no solution. Later, I happen to notice the "UE... Read more

Hello, I've been experiencing a string of bad luck with my Asus G75VW laptop.

Recently my 1TB harddrive showed signs of dying, so I pulled a 70gig harddrive out of an old laptop and replaced it till I got a new drive. A few days later the 70gig puckered out as well, I just wiped it and reinstalled windows and it worked for a day or two and then it failed again. I decided to pull another harddrive out of another laptop I had and after a few hours of it working great, my computer began to start freezing and then blue screened. After it crashed, I powered back up and now I can't see any options for bootable devices; no harddrives, no usb, not even my DVD drive. It does detect that the harddrive is there in the Sata Configuration. Also, the boot splash no longer appears when powering up if that could be a possible clue to my problem.

TL;DR After having a lot of harddrive issues, computer blue screens and now has no boot options.

I have absolutely no idea what I should check now, much love to anyone who can help me out.

Hi Guys,
I am not sure if this is the right place for this but here I go ...

I have just built my own home built machine (Spec at end of post) and I am having some problems installing windows 7. I have tested this system with my old 80gb IDE drive and I can boot into the ubuntu partiton so the rest of the system is ok.

When I try to install windows 7 it gets to "where would you like to install windows" and there are no drives available. I have checked all of the cables are plugged in (sata and power) and tried serveral SATA ports on the mother board but still no luck. The drive has also been formatted.

There are serveral settings in the BIOS for "PCH sata control" (IDE, AHCI, RAID (XHD)) and I have tried them all, when I set this as IDE the hardrive is visible in the BIOS where as either of the other two settings it is not. In all of these cases the drive is not recognised when I get into the windows install. The M/B guise suggested the AHCI mode.

I have also Tried using the M/B disk to install SATA drivers once I get to the windows install page also no joy.

I have checked the specs on the website I bought these from and they are both Serial ATA-300 compatible and the HDD is Windows 7 compatible. I am somewhat out of idea's here.

The only thing i can still see is that there appear to be two jumper pins on the back of the HDD but the HDD was OEM and had no manual and i cannot find any description of what they do if anything.

A:Issues installing windows 7 with Sata HDD

Read other 9 answers

Good evening,

Just installed Windows 7 RTM and my Sata HDD's and DVDRW are reporting as SCSI devices. I would get this problem in XP if I installed the mobo's raid drivers by accident. If I did then the devices would report as SCSI and the dvd burner would report as a cdrom and would not burn or read dvds

Whereas in Windows 7 the burner is reporting as a DVDRW scsi CDrom and will play dvd's and burn them too.

So at the moment there doesn't seem to be any problem however whilst navigating through the control panel I noticed the WEI. So I took a look and it's report my primary hard drive with a score of 5.9. The hard drive is a brand new Western Digital Caviar Black 500gb 32mb cache disk, is this score normal for such a drive?

Also is there anything else to worry about with the devices reporting as SCSI or is okay to leave it like that


Asus p5n-d nforce 750
Intel Quad Q8400 @ 2.66GHz
Asus ATI 4670 1gb

The only way to get a better score on your HDD would be to have either :

1) A 10,000 RPM drive, or for maximum scores,
2) A fast SSD (I have an Intel X-25M and get 7.7 as a score)

I have an old Athlon xp 2800 running XP sp2. After expanding its memory I had some "blue screen" events... I did some "house keeping" and apparently everything is fine again.

However, Windows seems not to recognize any devices attached to the computer. This applies to printer, sound, USB ports and even the network card (despite I could make it work after the house keeping).

When I open the Device Manager, it shows a blank page, as if there were no hw devices on the computer. Also, I tried to force a hw detection but it simply does not work.

I ran chkdsk /f several times and nothing was found...

I am afraid some windows files got corrupted.

Can anyone help with this?

Ever since installing Windows 8, I've been having issues with certain USB devices not working (when they were working fine in W7). I've installed all of the proper drivers for my system, and even made sure that it wasn't the devices failing themselves by testing it on two other systems.

First is my android mobile phone. All of the proper drivers load up when the device is plugged in. When USB transfer mode is enabled on the phone, the Android UMS driver will appear under device manager. However that's as far as it will go, Windows 8 will not access the sdcard through the driver (as it's supposed to, and does on both a W7 and XP system). Any attempt to access the device properties also causes severe slowdown and lockups until the USB cable is pulled from the phone's port.

Second is my printer's mulitcard reader (HP Photosmart C4180). None of the media's that are inserted in the reader will show up on my W8 PC, but will show up and work fine on both other PC's.

The drivers are up to date for all of the devices, it's just my W8 machine that doesn't want to work properly.

Is this through a hub or directly on the usb ports built in?

I just connected and disconnected my android device to the usb on my pc few times.
Then for no reason i heared some times the sound of detecting the device on/off automatic i didn't do anything but i could keep using the device on the pc.

And now again not sure what happened but now when i connect my device to the usb device it dosen't detect i at all and also other devices. No sound of detection nothing.

What i tried so far ?

1. Disabled/Enabled all usb controllers in Device Manager > Universial Serial Bus Controllers.

2. Restarted pc didn't work so now i tried to shut down the pc also didn't solve it.

3. I found window hotfix should be also for windows 8 but when i tried to run it i got message error it's not for my window. I have windows 8.1 pro. This is the hotfix i tried: https://support.microsoft.com/en-us/kb/2830154 not working.

Now i see another thing in the Device Manager i see yellow on: Unkown usb device, I tried to disable and uninstall it if i uninstall it it's gone. Tried to connect the device to the pc again nothing. Disable didnt work updating drive not working.
What else could make this problem ? I had the same problem few days ago so i shut down the pc and it was working again.
But now nothing help.

A:Windows stopped detecting usb devices how to solve it ?

Did you try deleting or uninstalling all the usb devices and rebooting? It is an old support trick to get Windows to reinstall the same driver. It seems to work as often as not.

If it does not work after that, at least for a short time, it may be a hardware issue.

Suddenly WM said that I needed to connect my devices before I could burn a CD. The thing is my devices are internal. It was working and then the next day it's not. Nothing has changed from what I know, no viruses have been found, no spyware, etc. I've tried uninstalling and reinstalling and microsoft.com has absolutely no help regarding this issue.

I had just reinstalled Windows 7 professional on my laptop (dell latitude E6440) because of some issues. Well the reinstall went thru perfectly and had no problems. But now it won't connect to the Internet and won't let me make a connection. A box keeps coming up saying "not connected-no connections are available". Then when I click on the Internet and try to set up a new connection it comes up saying "Windows did not detect any networking hardware". This kinda sucks so I was wondering if anyone could help me out and figure out how to fix this.

A little background info:
I had a friend of mine build this PC for me a few days ago, its custom. 
This is the motherboard I bought (new): Z-97A
I did a lot of upgrades so we had to do a custom install, I chose the default location to the same drive as my original W7 OS was on.
I installed all the drivers that came with the motherboard and all windows updates.
Even if they are not recognized the devices still get power (like my phone will charge but the PC doesnt know what it is or even see it as unknown)

I just purchased a new Seagate 300gb hd, and in addition to it a STLab Serial ATA PCI Card. I already had 2 WD 120gb hd's running in RAID 0 before this purchase.

So i installed the SATA card in order to add my 3rd drive since my mobo only supports 2. Originally i left my original drives attached to the mobo SATA connectors, and put the new 300gb on the card... however this cause the pc to try and boot from the new drive.. i guess the PCI slot must have higher boot priority than the mobo SATA connectors. I switched my old drives over to the new card and hooked up the new drive to the mobo. Everything booted up fine, and in the boot sequence all 3 drives were detected, however when i got into Windows, i could not see my new 300gb drive in Windows Explorer.

Should I not be able to see it here, and have the option to format it, etc. through Windows Explorer?

If someone could enlighten me as to what is going wrong it would be greatly appreciated.


A:Problems detecting my new SATA drive in Windows...

You will first have to create one or more partitions on it, won't you?

Use Disk Management to do so: Control Panel -> Administrative Tools -> Computer Management -> Disk Management. Your new (empty) drive will show up there.

I think you could have modified the boot priority of the S-ATA card vs. the on-board S-ATA, but that will likely depend on the BIOS - both the one on the mainboard and the one on the card.

1x Maxtor 300gb SATA HDD (Storage Drive)

My old IDE HDD died and so i opted to buy a SATA drive this time as i knew the performance was better and the drives are much cheaper now.
I've put the new drive into my pc, the SATA connector into the primary socket (the Maxtor storage drive has always been in the secondary and worked fine) and tried starting my pc and the install process.

Unfortunately setup "did not find any hard disk drives installed".
I checked my BIOS settings and the boot order between SCSI and SATA is correct (SATA 1st), and when passing the BIOS stage the HDD is showing up in my SATA drives list...

I've read around and understand that i might need a SATA driver disk to be able to install onto the SATA, but not sure if this is applicable to me as i have already used SATA in the past for my storage drive...?

I've tried pressing F6 at the start of the installation to get to the SCSI or RAID section, but i'm not trying to run the disks in a RAID array, so this seems pointless...?

All right, so here is the problem: I've been trying to install additional SATA hard drive on my computer, I've connected all the proper cables to mobo and power supply and at first it looked as if everything was fine, the hard drive was recognized by BIOS and Win7 but then Windows failed to find the driver for it and it disappeared. So what should I do?
The hard drive is WDC WD1600AAJS-00PSA0, mobo is ASUS P5E-VM DO, BIOS is AM ver. 0902, OS is Win7 Home Premium.
Important note: if I disconnect and connect the SATA cables the process repeats as in: Windows starts up, for a few minutes while OS is looking for driver the hard drive is visible and listed in disk management (I managed to format the drive just in case) but when it fails to find the driver it immediately disappears and I can't access it again.
The weird thing is that my main drive is also WD and it works just fine, no problems.

We have recently purchased a ZBook 17 G3 for one of our customers and it is required to have McAfee Drive Encryption loaded for security. With Windows 7 in Legacy mode, McAfee will install and encrypt the drive, but when adding another drive to the laptop, it does not see the new drive. When this was taken to McAfee for support, they say that the only support for the M.2 NVME drives is to have the operating system installed UEFI. We have a corporate version of Windows 7 that I have integrated all of the drivers including the NVME driver. I have then tried to create a UEFI boot manually per instructions I have found on sevenforums.com which is not working, I have also tried creating Rufus which neither is working that I have used in the past and it worked with no issues. I am at a total loss on how to proceed as I believe that during boot, it is not loading the USB 3.0 drivers and cannot continue to boot with the USB. The machine does not have a DVD Drive, so I cannot burn a disk to try and boot. I have incorporated the 3.0, and chipset drivers in the PE portion of the disk, and also the setup portion.

Hi, is it possible to install Windows 8.1 as Legacy with MBR? Or only as UEFI with GPT? I'm kind of confused with all this UEFI business, I always used MBR in my Windows installations. Also, Truecrypt does not support UEFI, so if installing Win8.1 I should do it as legacy.
Also, how can I control during the install process if I want to set my system installation as UEFI or Legacy?

A:Installing Windows 8.1 as non-UEFI

Yes, it installs fine with MBR on non GPT motherboards, and with UEFI - you need a motherboard that is UEFI 2.0 compliant - you may need to check your manufacturers documentation how to access the boot options.

so I've pulled all my hair out already trying to install Windows 7 on my Acer E1-510 laptop in UEFI mode.

The laptop came with Windows 8.1 preinstalled, and I've used that for quite a while before deciding to wipe it and clean install Windows 10.

The laptop does not have a CD/DVD drive thus I can only boot installation media from an USB drive.

The original installation was in UEFI mode, and in order to switch it to Legacy BIOS so I could install my Windows 10, I had to download an update for the BIOS which made such a switch available. It installed and ran fine for some time.

Afterwards I decided to switch over to mainly using Ubuntu. So I wiped the drive, saving only crucial data like photos and such to a backup USB drive. I have installed Ubuntu 16.04 in UEFI mode with GRUB2 as my bootloader. I swapped back to UEFI mode, and disabled Secure Boot.

Since some of my applications which I use are unavailable for Linux, I want to keep a Windows 7 x64 installation on a small partition in a dual-boot environment so I can reach for it if I feel the need for some of my applications.

So borrowed a friend's PC to clone my Windows 7 DVD to my USB drive in GPT format, so I can boot from UEFI. At first it was immediately giving a winload.efi missing error, the Setup couldn't boot, but when I re-imaged it to my USB drive it started to work.

It shows up a progress bar saying "Windows is loading files" and then reaches the animated logo. As soon as the an... Read more

So I recently purchased a Lenovo y480, along with a new hard drive to replace the rather slow 5400 rpm stock drive it came with (the new drive is a 7200 rpm Seagate if that is relevant). I wasn't a big fan of the time I spent playing around with windows 8, so I figured when I got the new drive I'd just put Windows 7 on there, along with Ubuntu 12.04.

I can get Win 7 to install fine in legacy mode, but I can't get it to work when installing in UEFI. Specifically, my install hangs at the "Starting Windows" screen. Here were the steps I went through to try and get it working on UEFI mode:
1) I enabled only UEFI mode
2) I disabled secure boot
3) I used the guide here:UEFI Bootable USB Flash Drive - Create in Windows to make a UEFI bootable USB drive. I used an .iso for Win7 /w SP1, and it installed fine while in legacy mode.
4) When booting from the USB, I go through a couple screens of "windows is loading files". When I get to the "Starting Windows" splash screen, it freezes up. This has happened several times, I allowed it to set there for a few hours as well just to make sure it wasn't trying to load up anything in the background.

I've tried a bunch of different tests (changing SATA from ASCI to compatibility, swapping out ram, disabling the wireless,optical drive,etc), but I still freeze on the "Starting Windows Screen". I was able to install Ubuntu just fine with UEFI enabled, it's just windows 7 that is causing the... Read more

A:Error on installing Windows 7 with UEFI USB

If you have a UEFI BIOS then make sure you've disabled Secure Boot, enabled UEFI Boot and try first with CSM or LEgacy BIOS or Boot disabled.

Make sure you've written the USB installation media correctly using Option One from UEFI Flash stick tutorial, in particular that the settings don't jump around when you add the ISO. Is the flash stick big enough for any updated Win7 media that contains all the latest updates?

Then boot the installation media as a UEFI device, which if it's set in BIOS and created correctly will be shown as an option for the flash stick. Follow UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums .

If problems persist report back all settings in BIOS related to UEFI, CSM, EFI, BIOS boot order, Secure Boot. Pictures will be very helpful, attach them using paper clip in reply box only.

I just upgraded my motherboard and cpu to

asrock H77 Pro4-M mobo

intel core i5 3550

the problem is I can't install windows 7 which I'm guessing is because of the UEFI but I can't be sure as this is my first time upgrading except for the storage more HDDs
I went into the UEFI menu and bothe the mobo and cpu were registered.
I have 3 HDDs.
one of them has a win 7 installation from before the upgrade.
when I Put the installation disk in it always tries to boot for the hdd where win 7 is installed
I Disabled all 3 HDDs in the UEFI menu and turned the dvd dive into boot option 1

now when it boots it says restart and use the proper boot order

A:installing windows 7 in new UEFI motherboard

In the UEFI, enable the HD on which you want to install the OS; also make sure the DVD drive is the first boot option. (I'm not sure whether you tried this or not.)

Put the installation disk in the DVD drive... then boot the computer. It should boot from the disk or at least give you a message to press a key to boot from the disk. Then you'll be able to proceed with the installation.

I'm preparing to install Windows 10 on my new PC. The motherboard is the Gigabyte Z170x Gaming 7. I have a quick question about a UEFI setting before I begin:

Under "storage boot option control" in the UEFI, I have these options:

- Legacy only (default)
- UEFI Only
- Disabled

I was told in the forums to make sure I install Windows 10 in UEFI mode. Gigabyte told me this board only supports UEFI - there's no legacy BIOS. Maybe I'm a bit confused. What is the "storage boot option control" for? Should I leave that on "Legacy only " or should I set it to "UEFI Only" for Windows 10?

Also, under CSM support:
Enables or disables UEFI CSM (Compatibility Support Module) to support a legacy PC boot process.
- Enabled - enables UEFI CSM (default)
- Disabled - disables UEFI CSM and supports UEFI BIOS boot process only.

Which one should I select? I already have "Windows 8/10" selected under "Windows 8/10" features. I'm using a 2TB mechanical drive, no SSD.

A:Quick question about UEFI before installing Windows 10


That MB supports both UEFI and BIOS mode . Hence CSM (Compatible System Mode or something along those lines)

For installing W10 with UEFI only disable CSM.
How you set boot control will depend on the media you are going to use for installation. Normally W10 installation media supports both legacy and UEFI modes.
You could try setting it to UEFI only and if it boots you're good to go.

Good day!I have the laptop possibly mentioned above, I did make a recovery USB in case anything would go wrong. My warranty has expired and I am not a newbie to computers, operating systems and such. I got sick of windows 8.1 on my laptop not being able to run old games, so I thought that I would have to install either Windows 7 or XP.I tried Windows 7, with USB stick and then with an external USB DVD Drive... None worked, because I got a "Load Driver" message, where it looks for the CD drivers (of course it doesn't have any). The BIOS barely has settings to enable CSM, Secure boot and to change the boot order, no other technical stuff that would help me proceed with my installation. The CD isn't corrupted, nor the ISO, because I do have an original key to use, so I am not pirating anything. Windows XP, also original, won't continue setup after loading the file acpi.sys, because it will show a STOP error screen about it. As mentioned above, I do not have a good BIOS to change ANY settings needed, HOWEVER the BIOS tells me that CSM can be enabled for INSTALLING WINDOWS XP OR OLDER OS. I cannot go any further than this by any meanings, but I am asking you if is there a compatible BIOS that I can flash so I can change more settings in order to install my desired Operating Systems. Regards,MettleSphee

I've tried easyUFEY WinToUS creator and AOMEI Partition Assistant Standard(Windows to go) with no luck.
My bios has UEFI option only(no legacy). On my old laptop it works just fine(I had the legacy option) but now, I cannot do that anymore.
I'm pretty sure it's a bios boot issue and I don't know how to fix it. I've tried using GPT partition instead MBR, Still nothing.

I have been procrastinating for the longest time, but I really need to get around to formatting the hard drive of my Asus laptop and installing a copy of Windows 7 on it, as Windows 8 has done nothing but irritate me since I acquired this laptop. Now I am not stranger to formatting drive c and installing Windows, but this will be the first UEFI computer I have to do it on. UEFI is a really screwy way of handling BIOS and I am not certain if this is going to cause me any problems when I attempt to replace the OS, so I would like a heads up on potential problems that might crop up before I attempt to format the hard drive.

Does anybody here have experiencing formatting and installing a new OS on the UEFI computer? Is there any advice you can provide or hazards you can point out before I get started?

Thanks for the help.

A:Formatting and installing Windows on a UEFI laptop

The issue will be to control the BIOS - - that's where the UEFI boot is enforced.
My reading suggests, that there is no option to disable UEFI if it is active (otherwise, there's no point to UEFI at all).

*IF* your bios can disable the UEFI option, then you will be

'home free' to reformat (even at the lower level rewrite of every sector to wipe the BOOT sector)
install per your own background/experience

It's embarrassing to say how many hours I have invested in fighting the UEFI on my MB. Anyway, I need some help understanding how and why you should choose UEFI when installing Windows. Windows 7 in this particular case.

I'll try to start by explaining some of the issues and some of the parts of UEFI I don't understand. let's begin with my boot options that has had me pulling my hair out.

Asus bios boot options look something like this

1.DVD drive
4.UEFI DVD drive (this particular option has caused me some major headache and I don't understand its use. If I try to install windows 7 using the UEFI drive it will disable my mouse at the Windows 7 install screen.
5.Windows boot device. Can't remember the exact label on that but it is usually tied to my SSD booting ability

The way I finally got my install to go smooth was to only have the first 3 boot options available. Disabling 4 and 5

Also, in my bios I can choose between Windows UEFI or Other OS? Right now I'm using the windows UEFI choice, although I'm doubting I'm fully utilizing UEFI since I did not install my copy of with with UEFI DVD drive

I guess what I really want to know is how to use UEFI? What is it? Why should I use it? and last but not least what is that UEFI DVD drive, why is this a necessary boot option?

Hey everyone,

Have any of you successfully installed Windows 8 with UEFI on a RevoDrive X2 (PCI-E express card)?

Any suggestions?
It starts the installation just fine for the RevoDrive X2 after loading it's drivers, but on first restart it...:

No boot drive found.Manually select to boot from the RevoDrive from the boot menu (F11), and it just restarts the installation again from scratch.

It installs and runs just fine with legacy BIOS (MBR) for the RevoDrive X2.

It also installs and runs just fine with UEFI on an internal SATA2 HDD.
Things I've done:

I own a Samsung R780 notebook with 08JA bios version, which has the UEFI Boot setting. The laptop comes with Windows 7 which I upgraded to Windows 8, but it was installed in BIOS mode, and I wanted to switch to UEFI. I tried to follow the instructions on the following website: Converting Windows BIOS installation to UEFI - TechNet Articles - United States (English) - TechNet Wiki

Unfortunately, after I followed all the steps, Windows didn't boot anymore, and it reacted like nothing was installed. Because of this, I wanted to do a clean install. After I booted in UEFI mode from the DVD, the Windows 8 logo appeared and before the very first menu appeared (where I select the language, time zone etc) I got a blue screen that disappeared too fast. I tried to record with my video camera and to play it, and found out the error KMODE EXCEPTION NOT HANDLED. I discovered that if I'm trying to start the installation in BIOS mode I don't get the blue screen. I tried to start the setup program in bios mode, and to partition the hard drive by creating one single partition as big as the HDD is, then I cancelled the installation, started the diskpart utility from the command prompt and executed the "clean all" command on the partition.

After all of this I was finally able to boot the DVD in UEFI. I partitioned the HDD how I wanted and when I started the installation I got another blue screen that I needed to record, with the same code as above: KMODE EXCEPTION NOT HANDLED... Read more

A:Blue screen when installing Windows 8 in UEFI mode

The article that you refer to seems to be an excellent piece of work - yet it still didn't work for you.

Are you able to reinstall Win7 in UEFI mode? Are you able to wipe/initialize the entire hard drive and then install Win7?
Are you able to install anything after turning Secure Boot off?
I also have seen discussion about the CSM setting needing to be disabled. Here's a link to the UEFI how-to at the Intel site: Microsoft Windows 8? - Enabling Secure Boot

I noted 2 things at the Intel link:
- Intel states that you cannot convert a BIOS install to a UEFI install - as such I have to wonder if the attempt made some changes to your hard drive/partitions that are now preventing the installation (that's why I suggested trying a wipe of the HDD).
- you don't mention having a efi file for your Windows installation (but it's required to install Win8). I have no idea if this is included on the installation DVD or not.

I have a Precision t7600 with A12 BIOS.  Asus hyper PCIe card installed with SM951 M.2 NVME SSD.
Currently the system runs flawless, booting from (2) RAID0 sata in LEGACY BIOS mode.
I installed the NVME on ASUS-HYPER PCIe card.  System recognized the SSD right away.  SSD  formats, copies, passes windows tool tests.  Yay - fun and fast.  Ok now I would like to boot from this fast SSD.
I physically disconnect mechanical SATA drives, from the system.
Create usb-thumb windows 8.1 install, and attempt to install to NVME SSD.  After the system partitions the SSD, I click "OK".  The first cycle install operating system to SSD - good.  The system reboots gracefully.  Normally after this step, system SHOULD NORMALLY boot from the drive and continue to install.  On MY system, will fail at this point:
 "No bootable devices--strike F1 to retry boot, f2 for setup utility Press F5 to run onboard diagnostics."
If I leave the USB thumbdrive in, it will automatically boot from the install USB and recycle the windows install from START again - and do this for eternity, instead of booting from the brand new install to the NVME SSD.
Going on day 3, really frustrated.  I can NOT get this system to take an install, in the UEFI, on the SSD.  I tried windows 8.1, windows 10 and Ubuntu 16, same problem each time.  I recently updated BIOS from A10 to A12.  I have tried to use RUFUS procedures to crea... Read more

You should be able to install Windows 7/8/10 with the default UEFI firmware (BIOS) settings.

Asus UEFI setups allow for both UEFI and Legacy BIOS (aka CSM) booting to be enabled. In that case, Windows 7 can normally be booted with the motherboard's Secure Boot feature enabled as well, but without actually using it.

CSM (Compatibility Support Module) > Launch CSM
- [Auto]: The system automatically detects the bootable devices and the add-on devices.
- [Enabled]: For better compatibility, enable the CSM to fully support the non-UEFI driver add-on devices or the Windows UEFI mode.
- [Disabled]: Disable the CSM to fully support the Windows Security Update and Security Boot.

Secure Boot > OS Type
- [Windows UEFI Mode]: Execute the Microsoft Secure Boot check. Only select this option when booting on Windows UEFI mode or other Microsoft Secure Boot compliant OS.
- [Other OS]: Get the optimized function when booting on Windows non-UEFI mode, Windows Vista/XP, or other Microsoft Secure Boot non-compliant OS.

I am trying to instal Windows 7 Ultimate on a 4T HDD using UEFI. My HDD is already GPT it had 3 partitions 1 set at 150g another set at 750g and the other set at 2xxxg. The 750g and the 2xxxg both have data stored on their partitions, so I don't want to delete them. So, I deleted the first parting that is 150g. Then I clicked on new, Apply (for full size of disk), and OK. It creates a total of 3 partitions out of the 150g of space that there was. So, i now have a 100.0 MB System partition and a 128.0 MB MSR (Reserved) partition and the rest of the 150g was turned into a 3rd partition. This now give me a total of 5 partitions on that drive with the 2 that have saved data on them. I select the 3rd partition (the one that is almost 150g) and I then click Next. It goes through it's first windows install where it expands the windows files. After it is done expanding the files it says that it will restart in 10 sec. All these seems to run like normal (like the normal non EUFI MBR installs do). when it restarts it does NOT go to the next step of finishing the instal where you would pick your username. What it does is 2 different things based on "I have no clue". Some of my attempted instals at this point will take me to a black screen saying that it can not find the boot device.

Im wondering if when windows is creating your additional partitions during setup it creates more than it should and that triggers the error when rebooting ???

It is possible to use diskpart to create a primary partition yourself during setup and then tell windows to install there which eliminates the need for the system reserved one but im not sure about the MSR one (I don't use GPT or UEFI) im not 100% if this will help just thought it may be relevant

Sorry, but it sounds as though you have a physical hardware problem. Without opening up the computer and doing advanced and expensive repairs, there is no way of fixing this. You will just have to live with 1 USB port. You could however buy yourself small USB splitter so you can have more than 1 USB device plugged in at once.
