Problem installing Windows 7 onto External HDD

Can you confirm you've disabled Secure Boot?

I asked you if WIn8 will still boot in Legacy? Normally you'd need a Dual CSMode.

Otherwise you'll need to follow the steps in the tutorial to install in UEFI mode trying to get the UEFI DVD drive option to show, or try UEFI Bootable USB Flash Drive - Create in Windows

No Legacy mode doesnt load Win8. Maybe if I update my BIOS? I'll try that guide tmr, I'm gonna get some rest now. Hope that guide works, if not what would you recommend me? Thanks for the help btw :)

I asked Theog to look at this when he comes by in the morning. He may have some other suggestions. But you'll need to follow the tutorial.

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.

Are you following UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

If UEFI is enabled you should have Windows Boot Manager and UEFI DVD choice in BIOS boot menu. Did you enable Legacy BIOS losing those choices? Will Win8 still boot?

If you have Compatibility Support Module (CSM) you can choose Dual Mode but I would not go full Legacy unless you decide to Bypass UEFI to Install WIn7 which would require reinstalling Win8.

I tryed both modes, Legacy mode will show the DVD. Dont think UEFI shows any boot options (I think boot manager only, no DVD/CD). Nope, my BIOS doesnt have CSM. What shall I do? Nope I didn't follow that guide.

For internal HD.
The above sounds look you trying to boot Windows 7 x32, & not Windows 7 x64 for UEFI install, check your DVD.

Warning you must have the uEFI/BIOS firmware setting in Step Three set.

3) Reset BIOS to default, and reboot to BIOS make sure Secure Boot is disabled.

NOTE: Check your manufacturer's uEFI/BIOS firmware manual for settings.

For External 1TB Samsung M3 HDD, take a look at:
Windows To Go - Create in Windows 8 Enterprise

Windows 8 To Go - Setup on a USB Flash Drive or USB Disk

Portable OS - Carry your OS on an External Drive

I dont see the "Make sure CSM is ENABLED, & set to UEFI boot." option in my BIOS. I've checked everywhere, maybe thats the main problem...

I'm on a Acer Aspire V3 571G laptop.

No Legacy mode doesnt load Win8.

How do you know, when CSM not ENABLED?

I dont see the "Make sure CSM is ENABLED, & set to UEFI boot."

Did look at the ACER video?

Looked at that from the start, I've updated my BIOS version. Let's see if I have any luck. There was no CSM option at all in the BIOS.
