Acer laptop, uefi, no bootable devices found

[kingkong111]

So, got a new laptop, and it started to rain in problems :
1) uefi - what kind of crap is this ?? it cannot detect anything - i have ssd, i have pluged bootable win7 installation usb flash, but it just gives "no bootable device found". Had to turn off uefi and enable legacy mode. Is uefi usable only with windows 8+ ?

This is the benefits of UEFI:

• Better security by helping to protect the pre-start-up – or pre-boot – process against bootkit attacks.

• Faster start-up times and resuming from hibernation.

• Support for drives larger than 2.2 terabytes (TB).

• Support for modern, 64-bit firmware device drivers that the system can use to address more than 17.2 billion gigabytes (GB) of memory during start-up.

• Capability to use BIOS with UEFI hardware.

i have pluged bootable Windows 7 installation usb flash,

You need to use a Windows 7 x64 DVD, as Windows 7 installer has no USB 3 drivers.

 

[kingkong111]

But i have pluged my flash into usb 2.0 port, or uefi doesnt support that too ? ...

Have you reset the UEFI/BIOS to suit Windows 7 x64?
Downgrade Windows 8 to Windows 7

On some Acer, Gateway, P. Bell, Windows 7 x64 will not install in UEFI mode.

Yeah, with uefi, boot menu is empty, and the only option to boot something is to disable uefi.

are you positive you bootable drive works? and it is configured properly?

 

[kingkong111]

Yes, it works, i made it with windows 7 dvd/usb tool.

 

[HarriePateman]

okay try to disable the UEFI mode as you suggested install windows then enable it again.

Yes, it works, i made it with windows 7 dvd/usb tool.

The Windows USB Tool will not make a UEFI bootable USB drive.

Using a USB Pendrive on a PC with a uEFI BIOS.
USB Pendrive need to be formated to FAT32 as in
UEFI Bootable USB Flash Drive - Create in Windows
Take note of Step 11 for Windows 7.
Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.

I came back to the thread to mention that, after some research... You beat me to it!

This trick doesnt work.

And that step 11 is to create uefi bootable device manually, i assume, that tool rufus works good too ?

 

[HarriePateman]

I would follow step 11, and do it manually.

 

[gregrocker]

Use Rufus from Option One of UEFI Bootable USB Flash Drive - Create in Windows which automates the file edit and always works.

Then report back the BIOS settings choices for UEFI, CSM, Legacy BIOS, Secure Boot and BIOS Boot Priority choices.

You may also need to reset the BIOS to defaults before doing this. Is there more than one reset choice?

 

[HarriePateman]

Okay so i just re-installed windows, using the Microsoft Usb Tool.

Smooth no problems...

 

[kingkong111]

So, i tried that rufus tool, and made win 8.1 installation uefi usb flash, and it worked - booted and installed successfully.

 

[gregrocker]

The difference is that the Rufus tool works best for UEFI since it automates a file edit that is easily messed up when done manually.

For Legacy BIOS one can use the MS tool.

Hi.
I have an Acer ZS600 All-in-One touch screen, Changed HDD to 2tb. Windows 7 setup by Rufus on USB flash.
Issue is No keyboard input from USB so can’t press F12 so need drivers and where to put them when I can’t boot from USB.
Can you direct me to the proper post?

 

[SIW2]

You could use this. You don't need to download simplix.

Just run it without simplix pack and it will integrate usb3 and nvme drivers.

Update your Win 7 installation media

 

[EastCanMan]

Ok, thanks. I will give that a try and update you when I get home...
