I am running a self-build  desktop PC. Any suggestions please

EasyBCD is free & easy to use from your W10 installation. Just add your W7 Drive & you're off to the races.

You'll hafta set your W10 HDD as 1st boot device in BIOS so that you don't hafta select F12, for this method.

 

Method #2

 

Have you tried to select your W7 drive for booting via F12? You MAY hafta fix your W7 installation boot.

Use your install disk as if you were going to reinstall, and on the 2nd page select Repair my computer, then use other recovery options & choose command prompt.

 

To keep your windows 7 HDD as 1st boot device

Insert the following followed by enter on each response:

 

 

bootrec /fixmbr

bootrec /fixboot

bootrec /rebuildbcd

Notice the space between bootrec and the / symbol

On the rebuildbcd entry it should scan your drives for Windows installations & find 2, so select A for add all.

Dave's right, its the easiest to use I use it too, it will also rename the drives display name too so if you dual boot similar builds they are easy to tell apart. PeAcE

Easy BCD has to be installed on ea OS that you want to use it on.

so if your master boot is Windows 7.

install easybcd. 

it should add to the desktop so you can then OPEN it.

then add a new

then once you add the new one edit to chang eht name so you know what one is what

then you can rename and select the one you want to boot to

save setting then exit  and then reboot  it will auto select the OS you selected.

thanks guys sorted it. I had installed easybcd 2.3  to both drives neither would open to let me change boot system. I uninstalled them and downloaded the earlier version 2.2 installed on both drives they opened alright did the necessary alterations . went into the bios reordered the hard drive order, restarted PC Bingo the duel boot screen appeared  all is fine now. Thanks  guys for giving me some ideas on what to do :fc:

Have you considered running just your primary OS from your hard drive and using VM or Oracle VirtualBox when you need to access the other?
