hi im new here and not sure if i can join this thread or if should start a new thread so if im in the wrong area please say so. i bought an Acer Aspire One 725-0826 for my girlfriend, it came with windows 8 pre-installed and shes really not liking it. as you probably already know it doesnt come with cd/dvd drive so im trying to install windows 7 ultimate sp1 x64 via usb drive. i've tried several tutorials for both uefi and legacy mode with no luck, legacy mode doesnt detect the sata drive and this is what i get when i try in uefi: Windows failed to start. A recent hardware or software change might be the cause.
To fix the problem:
1. Insert your Windows installation disc and restart the computer.
2. Choose your language settings and click next.
3. Click "repair your computer"

file: \efi\microsoft\boot\bcd
status: 0xc000000d
info: an error occurred while attempting to read to boot configuration data.

i noticed some other people were having this same problem when trying to install win7 in uefi mode but i havent found any solution for it. all the tutorials looked promising at first but this is going on week 3 now and im about ready to give up. so frustrating.
any help would be appreciated, thank you

On some Acer, Gateway, P. Bell, Windows 7 x64 will not install in UEFI mode, you need to use Legacy mode.

Enabling the boot device menu

Acer said:
On most Acer systems, you can use the F12 key on boot to select the drive or network from which loading the operating system. In case the F12 option does not work, you may need to enable this function.

SOLUTION

Enabling the F12 function:

1.Power on the system. As soon as the first logo screen appears, immediately press the F2 key, or the DEL key if you have a desktop, to enter the BIOS.
2.Press the right arrow key to select Main.
3.Use the arrow keys to navigate to F12 Boot Menu, and press ENTER.
4.Select Enabled, and press ENTER.
5.Press the F10 key to save changes and restart the system.

the acer aspire one 725-0826 has a insydeh20 setup utility which is a bit different from the bios shown in the video but through other tutorials i figured out how to disable secure boot & enable the boot device options. only after making these 2 changes did the bios even recognize my kingston datatraveler but still wouldnt boot from it... instead i got the message that i first posted. thats where i was stuck.
oh and this bios doesn't have a launch CSM option, or if it does i cant find it.

looks like it has one usb 3.0 and thats the one i've made most of my efforts on. i also made several attempts last night using a 2.0 slot with no luck. i really wanted a fresh install of Win7 but it looks like downgrading is my only option. im going to give that a go tonight. thanks for pointing that out, i had no idea.

Hello Habs, and welcome to Eight Forums.

For now, you might see if this may be able to help to downgrade to Windows 7.

Hope this helps, :)

i followed the the tutorial to downgrade to Win7 but i'm stuck at step (4) with the same error message. forgive me if theres something obvious im missing but i just can't figure it out. the only way i can even get to step (6) of the "downgrade to windows 7 tutorial" is if i boot in legacy mode which is useless because there are no drives detected in the list to install Win7 on. grrr!

would you suggest i delete all partitions and convert the entire drive to MRB or should i create a new partition & convert that to MRB?... leaving Win8 incase this doesnt work. im just worried i might be left without any functioning os.

You cant convert a partition - you can only convert the whole HD.

If you use the linked pw boot media, it shouldn't delete anything, it just coverts.

If you are concerned. might be a good idea to make an image first. Free macrium or Aomei will be fine. Unless you have done that already ?

You could create another partition on which to install win7, leaving everything else intact.

Then covert the drive to mbr. If you have more than 4 partitions, some of them will be converted to logical drives inside an extended partition. That is ok. You can install win7 to a logical drive.

i might of discovered something,... i've been using rufus to create my bootable usb drive and in a couple of the tutorials i found it said to prepare the usb drive using "GPT partition scheme for uefi computers". only after you mentioned converting the drive to MBR got me thinking maybe my drive is already MBR, so i tried one more time to create a bootable usb drive with Win7 but this time i selected "MBR partition scheme for bios and uefi computers" and changed the file system to NTFS... sure enough it boots in legacy mode and Win7 installation detects all partitions. don't want to celebrate too early, gonna make sure i have all my recovery & repair discs first then try the installation. ill get back to you soon.

Solved.. this is what i did: 1)using Rufus i prepared the usb drive with a MBR (not GPT) partition scheme for bios or UEFI computers in NTFS format.
2)then in the bios i changed the boot mode from uefi to legacy, allowing Win7 installation to detect the drive and all its partitions.
3)like SIW2 said i had to delete all partitions and format the entire drive converting it to MBR and making it accessible to Win7 installation.

Minitool partition wizard is a great tool but only allowed MBR>GPT not GPT>MBR, so i used Minitool to delete the partitions and the Win7 installation to format the drive changing it to MBR.

it all sounds simple enough but my lack of experience with UEFI computers and GPT drive types is what complicated things for me.
no matter how much reading i did, i probably wouldn't of solved this without you guys. my girlfriend and i thank you all so much, she now has a workable computer with Win7.

ps. is it just me or are they still selling notebooks that aren't fast enough to support the os.
1ghz processor with 2gb ram running Win8, seemed sluggish to me and not to mention made for a tablet not a pc.

anyway thank you all once again for your guidance, couldn't of done it without you.
