Clean install of Windows 7 on Ultrabook fails

So I get a new ultrabook, the Fujitsu UH572, and promptly plug in my usb stick to do a clean install of Windows. Windows sees 2 drives: a 32GB ssd as Drive 0 and a larger spin drive as Drive 1.

Creating a new partition on Drive 1 doesn't create the expected "System Reserved" 100mb partition on the same drive. It creates it on Drive 0! The installation proceeds but upon reboot the ultrabook will not boot! This cycle repeats with various attempts to patch it on my part (including manually partitioning via diskpart).

The solution? Load the "SATA AHCI Controller Drivers" before partitioning the drives. Once the drivers have been loaded the much bigger spin drive shows up as Drive 0 and Windows installs properly. The drivers are in the files\irst\Drivers\x64 folder of the driver download self-extracting executable. The necessary drivers can be downloaded from Fujitsu's mobile support website.

*whew* For a few hours this ultrabook was looking like it'd be a glorified paperweight...


  1. OMG Thank you so much! I was ripping my hair out trying to figure this out and I also thought I had a glorified paper weight!

  2. Thanks for this article! But it took me another two hours to solve the problem that my Lifebook/Windows 7 wouldn't accept additional SATA drivers for the installation. The solution was so simple: I tried to install Windows 7 from an USB 3.0 stick with the USB 3 ports on the left side. As soon as I swapped the same stick to the USB 2 port on the right side everything went smooth ...

    1. you know, at the time I did this I didn't have a usb 3.0 stick so didn't encounter this. But I totally believe it, usb 3.0 is pretty new, usually takes a while for drivers to get the kinks worked out.

      I still want to see how long an install takes with usb 3.0 though :)

  3. Cheers for a good post! Been cursing fujitsu while trying to do a clean win7-install.. You're a life-saver! (or, "hour-saver").. :)

  4. I had a New one With ssd and msata and it gave me the error no matter what, so i took out the ssd and installed 8.1 on it using a different Laptop, i put it back in and voila. pain in the ass...

  5. Thanks so much, stupid Fujitsu U772!

  6. Thank you so much.
    You are very helpfull

  7. I can only install on the SSD. If I try the harddrive it says it is a GPT partition and that windows cannot be installed on GPT.

    I like the idea of having the OS on my 32 GB SSD drive. If I install Windows 7 on the SSD it just loops back to win 7 installer after first restart. If I install Windows 8 and leave the stick in long enough for the "boot from USB..." notification to appear I can boot from the SSD and windows 8 works great! Much faster than before.(No I have not installed Win 8 on the thumbdrive it is on the SSD Drive 1). However if I don't have the windows 8 stick in the USB it just says Bootable device was not found. I have bios 2.08. I can not find the SSD in the Bios so I can not set Bios up to boot directly from the SSD without fooling bios by having the thumb drive connected for a second at boot up.

    Any ideas on how to make SSD bootable?

  8. Johan, on my system, the BCD was installed to the USB drive from which I installed Windows 10, so that USB drive had to be inserted to boot the computer to a Windows 10 installation on C:, which was the MSATA 32GB SSD. The 500GB spinning drive was F:, and I wanted to use this for file storage.

    The problem was that on the Fujitsu UH572, the 32GB SSD was not bootable in the BIOS. Only the 500GB spinning SATA drive and the USB stick were bootable. So I needed to create a BCD on the 500GB (F:), which pointed to Windows 10 on the SSD (C:). Previously, this job was being performed by the USB stick. I could see this using EasyBCD. There was only one BCD store, and it was on the USB.

    I used the BCD deployment option in EasyBCD to create a new BCD on F:, then I created a new entry to load Windows from C:. The computer then booted correctly to C: without the USB stick inserted.

  9. Wow!! I stuck on this problem for about 2 days! And then i reach this post - i ever don't remember how - and problem solved!!!
    Thank you so much!!!

    BTW - if anyone need this:
    Load the "SATA AHCI Controller Drivers" means that add the drivers files to the bootable USB and then when you boot from USB and go to the Windows installation - you can select "Load Driver" in the partitions screen - then browse for the folder in the USB and problem solved
