Changing a laptop from Win10 to Win7 -- BIOS issues

#1
I'm trying to "upgade" a new Acer TravelMate laptop from Win10 to Win7.
Unfortunately Acer have locked the BIOS to prevent booting from USB or DVD.
Despite having followed advice and having disabled secure boot, set administrator password etc, it still won't let me boot from USB or DVD.

I have seen some stuff that says many Win10 machines are now effectively locked from removing Win10.

Any useful advice welcomed.

I`m far from being an IT expert but isnt Win 10 the later/better version?

No. It has more spyware than the Kremlin and horrible apps.
I'm very happy with Win7 which is less trouble than Win10

Pretty much my understanding of it.

Something else to consider is even if you do manage to get Win7 installed, a lot of hardware now is not compatible with it, so you might have issues running it without fault.

Unfortunately Windows is smarter than that and locks itself to the CPU serial number on installation.

But if your only fitted HDD has W7 on it, are you still locked out? Or do they have DB of the CPU's that have previously been installed with W10? That sounds dodgy from a legal perspective...

Windows 8 and higher OS uses UEFI mode and has GPT Disk Partition type by default. Therefore installing windows 7 and lower OS that is BIOS Based and uses MBR disk partition takes some proper configuration to be successful.

I ran into the same problem when I changed from Windows 10 (due to it's current flaw -the increased internet usage through background apps and system updates) to windows 7.

Although it is marked solved, I still taken the time to add my comment hoping to help future readers of this thread.

UEFI has feature called safe boot which adds extra layer of security to loader and it prevent booting from external sources like bootable USB Drive or CD. Therefore even you make Bootable flashdrive or CD it won't show up on boot menu or booting process.

Prerequisite:
Backup all your necessary data to an External Disk Drive/Flash Drive/ or another Unit. Do not just backup on the same disk with different partition because you might end up deleting all current partitions on the disk to install a fresh copy of Windows 7. See note below.

What we can do:
1.Disable Safe boot and change Boot Mode to CSM/Legacy BIOS Mode.
2.Make a bootable USB Drive/CD that is acceptable/compatible to UEFI.

1st Option: Disable Safe boot and change Boot Mode to CSM/Legacy BIOS Mode.
1. Load BIOS Settings page ((Head to BIOS Setting on your PC/Laptop which differs from different brands. Usually by striking [F2] key upon loading the unit and before the OS logo appears on the screen. Just search on net how to go to your BIOS settings based on your brand.)
2.Disable Safe boot option from BIOS security settings.
3.Find on your BIOS Settings about Boot Mode, change from UEFI(Unified Extensible Firmware Inferface) boot to CSM(Compability Support Mode)/Legacy BIOS mode boot. Remember that UEFI uses GPT partition type and CSM uses MBR. (Reference on GPT and CSM on link below)
4.a From BIOS Boot Order make the USB as the first priority/first boot.(Remember to revert this option after the installation to prevent future error when booting Unit with attached USB Drive on its port).
or
b. You may skip 4.a and just press the Boot Option Menu Key before OS logo appears during booting. It's usually [F8] or [F10] or [F11] or [F12] on the most brands. Then select USB from Boot menu from options.
5. Save and exit from bios
6. Boot from installer and Install OS.

Note:
If your current OS is windows 8 or higher, as I said it uses GPT partition type disk by default not MBR thus you need to make the Disk converted into MBR or erase All Partitions until the disk is fully unallocated (means losing all your precious files) then create new partitions for your windows 7 System and Data Drive.

2nd Option: Make a bootable USB Drive/CD that is acceptable/compatible to UEFI.

Ah!

I seem to recall that I had to do something like that to install Linux on a fairly new [W10] laptop.

Done all that stuff but there is no BIOS option for CSM, only UEFI.
I would normally use something like Hiren's boot cd to strip a HDD, not sure how to do this in Win10, or even if I can do it using the installed disk management tool.
I have backed up the HDD (disk image and a recovery DVD) but erasing all partitions sounds a bit nuclear.

What is your actual model number ?

Acer Travelmate P2410-M, Core i5
Have been on the phone to Acer technical support and they tried several ways to re-set the BIOS, none of which worked.
Machine being returned to Acer.
