Acer, "No operating system found" after going into BIOS and enabling Legacy BIOS mode with Ubuntu as the only Operating System

[bidkar159]

Hello,

I have an Acer V5-471P-33216G50Mass which I had bought in 2013, it came preloaded with Windows 8, which I upgraded to Windows 8.1
Overall, I never had problems with the laptop besides the usual slowness. At one point I dual booted Linux Ubuntu, and after using for a while, I deleted it.

About 4 months ago, I upgraded to Windows 10, and after some use I encountered a bug that rendered it useless, so I downgraded back to Windows 8.1, I was really frustrated, and at the moment my laptop was being slow, so I completely wiped my drive and installed Linux Ubuntu, which is currently my only operating system on my computer.

I really did like Ubuntu but it turns out that many programs that I use are not available with Linux, and I wanted to go back to Windows. I couldn't really find instructions on how to do that on Google, so I tried a recovery USB from Microsoft as well as Linux, and they all reverted me back to the Ubuntu loader, I tried to go into BIOS and change the order in which to boot up (Linux, windows, drive, etc.) but it would not keep the change and it would revert back into its previous state.

In my frustration I enabled Legacy Boot, which after restarting my computer I get the following screens:

1. Acer boot up screen. It does say "Press F2 for set-up" but when I press it nothing happens except a quiet long beep noise.

2. It lists the processor specs? It lists something "Intel'

3. It says on the top let corner: "No operating system found"

4. When I have something inserted (like a USB) it says to: Remove media devices" and then proceeds with step's 2 & 3.

I have tried turning it on & off, and different variations of F2.
I read in another thread to do the following and have ordered the cable to get it done, but I do not know if it will work.

*****“I had the same problem this works if your hard drive is formatted and your computer does not recognize when you want to install.
Solution 50% it might work and plus and if running windows 8 you will lose your LC key, if you have the CD/DVD the LC Key will be on your Disc check before doing it.
You have to have USB 2.0 to SATA IDE 2.5 3.5 5.25 External Adapter Cable,.and another computer

1. take the hard drive out of your laptop/desktop Check if everything is properly connected it might be misplaced.

2. connect the External Adapter Cable to the HDD (Hard Drive) to another computer and wait till the computer recognize the HDD. If it does not recognize check the cables if it does not most probably your HDD is Dead

Note: you can back your files from there if you have any important files, like picture, documents.

3. after the computer recognize the HDD click start manu and type computer management and click on COMPUTER MANAGEMENT go down to Disk Management and search for your Disk (HDD) that is connected with the External Adapter Cable.

4. right click and click delete the volume make sure you the delete every singlle volume till it tells you Unallocated Drive or Unallocated Disk

5. disconect the hard drive and put back in your Laptop/desktop and reinstall you Windows angain. For windows 8 F12 To Boot With Acers F2 for Bios To Turn the SECURE MODE OFF and UFF so you you can install windows 7 if you want.

I have Acer warranty, but I don't bellieve this is something they will cover, at the moment, I do not have the money for a new computer, but I will start saving if it comes to that.

Any advice?

Thank-you

1) The reason your computer is slow is because the i3 chip in there is seriously under-powered. Had nothing to do with the OS, though software you added certainly could have made things much worse.

2) The grub loader (or whatever loader you picked) overwrote the uefi while your system still had UEFI enabled. That could cause it to skip everything other than itself for sure.

3) You should try going back to the BIOS and making sure that USB boot is enabled and above all other options. Press F10 to save (or save and exit), and then try with a usb made with the instructions at http://windows.microsoft.com/en-us/windows-8/create-reset-refresh-media

See, my problem is that I cannot access the BIOS, when I press the F2 key as prompted I get the steps I posted above:

1. Acer boot up screen. It does say "Press F2 for set-up" but when I press it nothing happens except a quiet long beep noise.

2. It lists the processor specs? It lists something "Intel'

3. It says on the top let corner: "No operating system found"

I don't know any other way to get back into the BIOS.

Try removing the battery and hard disk (and power cord), then after a minute or two turn in on (battery or external power, your pick). You might be able to access the BIOS once the system figures out there's no disk at all.

With or without the battery I am still getting the same response, I have linked pictures. This first picture is the is the first screen that comes up after the Acer screen and then the second in the same order.

Looks like you enabled pxe boot for no reason and it's trying to boot from a network drive that wasn't configured. Go into the bios and disable pxe boot and make sure the boot order has your disk up front (or EFI boot manager)

Unfortunately I cannot access BIOS at all, when I press the F2 key, alI i get is a solid beep sound and the screens I posted about show up. :/

You will have to see your manual about what buttons to press, but if you can't get into the bios directly you might be able to press the boot menu combination to select your drives that way.
