duel boot on Acer fail

You guys are great! making backups. . .
can I make these backups on my portable usb drive?

can I make these backups on my USB portable?

Dammit, can't make recovery disks on USB portable through Win8 nor through Acer rocovery

The Windows Recovery USB drive & Recovery Partition can be very problematic, I recommend you also make a Windows System Image.

System Image - Create in Windows 8

Recovery Drive - Create with USB Flash Drive in Windows 8

System Repair Disc - Create in Windows 8

System Image Recovery - Restore Image on Computer in Windows 8

or
look for a 3rd party ,Backup software, which fully supports Windows 8/8.1, uEFI, GPT & Secure Boot.
Which is signed by Microsoft.

Windows 8 will activate with the license that came on that PC when/if you reinstall it.

What I would do first after enabling Legacy BIOS is boot into installer to wipe the HD with Diskpart Clean Command as you don't need anything that's on there and would be reverting to the worst possible install one can have to go back to a factory preinstall of any OS.

Instead do a perfect Win7 install following these same steps for Clean Reinstall - Factory OEM Windows 7.

Test Win7 on the machine to see how it runs. If you still want Windows 8, save a space on the HD or shrink Win7 in disk Mgmt to Clean Install - Windows 8 which will configure a Dual Boot.

Since you're installing in flexible Legacy Mode without the troublesome UEFI crapware, we can help you remove either OS at any time going forward. Only if you decide not to keep the machine or need to ship it back for service may you need to run Factory Recovery or the backup image you save of the UEFI factory bloatware install.

Hey tnx guys! your advice was impeccable. My system is purring like a kitten and with the exception of missing drivers in Win7, everything is smooth sailing!

Did you run all Important and Optional Updates to completion, after enabling Automatically deliver drivers via Windows Update (Step 3)? Check for UPdates now to be sure. Double-check Optional.

If so then import the missing drivers in Device Manager from the Acer Support Downloads webpage for your model. If there are no Win7 drivers, first try Windows 8 driver for your bit-version. Google the device for Windows 7 drivers. If no joy post back for more help.

Hey thanks man.

Unfortunately the win8 drivers supplied on the Manufacturers' website did not work on Win7, and they did not support win7 on my model, however, I tried the Win7 drivers for my laptops predecessor and it all worked out fine. Thanks again everyone that helped! I can't tell you how much it meant!

You're most welcome. Let us know how Win7 runs on that laptop.
