Can only dual boot Windows 7 with windows 10 using F8 key

Hey guys

Bit of a mission with driver signature errors and needing to convert ssd drive to mbr but I got there and have windows 7 installed a new ssd drive.

I have windows 10 on another ssd drive installed already and the only snag at the moment is having to press f8 to avoid the windows boot manager (and choose a boot device) which only shows windows setup and windows 10 as the boot options.

I've read this about bcd editor or something but last thing I want to do is screw up the system at this point.

I have a sabertooth 990fx r2.0 motherboard. Tried looking around for options but am a little stuck.

Advice welcomed!

Many thanks

Marc

I've used the Easy BCD program many times without any problems. When I had dual boot 7/10 and now dual boot Win 10/Win 10 Insider.

EasyBCD Download

Alas whilst I can get a nice looking menu using this with both OS displayed I get the age old Error:0xc0000428 Digital Signature for this file couldn't be verified (windows\system32\winload.efi)

EasyBCD has a pop up which says as i'm booting in EFI mode which means there are limitations.

I honestly don't want to mess up my pc for the sake of hitting F8 after switching on but if there is a simple and safe method of getting me to the holy grail please let me know!!! :)

Cheers!

Hi All,
Greets,
@ mcbgun : Sir, In the meantime consider these two :
1) this post ( Follow Sir NavyLCDR in particular ! ) :

2) make a system image & rescue disk with Macrium Reflect Free before doing anything else :

Please edit your Profile with ALL your hardware specs.

If you have a system that is booting as UEFI, you should use Manage EFI/UEFI boot options & Manage EFI System Partitions & Fix EFI/UEFI boot issues the easy way!

Open disk management and on the View - Top - Disk list. On the partition style you going to find if it is a GPT or MBR.

Expand the columns so we can read them and take a snapshot with the snipping tool of the whole window.

Apologies for the delay....I have updated my profile with hardware specs and will look at your link in this post over the weekend.

I had converted the SSD drive to MBR before installing windows 7 in any case as I ran into the issue of GPT when trying to install Windows 7 on it originally before posting on the forum.

Many thanks again all for your replies!

If you have two separate drives, one for each OS, then in my view, the easiest way to achieve a successful dual boot is to get a SATA power switch, so that you can turn one drive off while the other is on. Then, when you want to boot to the other OS, power down, turn the current drive off and the other one on, then power on. Like magic, you will be in the other OS. That's how my computer is set up, with an additional detail: I have a third hard drive, for my data. It always stays on, so that my data is available in both OSs.

Here's the SATA power switch I use:

Amazon says it is currently unavailable.

Some of the comments indicated that the newest version of this switch has issues. That's a shame, because the one I have works like a champ.

Waiting for the Disk Management image. Expand the columns so we can read them and take a snapshot with the snipping tool of the whole window.
