changing the boot

[macgru]

I have an old 2011 imac 21 inch. It keeps booting into disk utils i reinstalled osx and restarted it said startup disk. So i choose Lion os but it goes straight back into disk utils. I have checked the disk using first aid it says everything is fine. Is there a way to make it boot into the OS

What do you see if you hold Option at the boot chime?

I see Macintosh hd which i select still goes into Disk utils

If you have another Mac available then I'd suggest downloading OS 10.13 (the latest officially supported on a 2011 iMac) and then using the createinstallmedia tool to make a bootable USB drive. Install that, rather than trying to mess around with the ancient version 10.7.

Edit: It seems that the forum has broken the link to the OS. It should be macappstores://apps.apple.com/app/macos-high-sierra/id1246284741?mt=12

I would do that install from a bootable external OS X installer, not from the recovery system.
And, I agree, 10.13 (High Sierra) would be your best choice at this point.

I can't quote a reference, but my memory is that there are problems with Lion from Recovery. Much easier to install from a bootable USB (can be an 8GB flash drive) as suggested above. And yes High Sierra.

If the App Store (as suggested by @Nermal) won't offer you High Sierra, get Sierra from section 5 of https://mrmacintosh.com/how-to-download-macos-catalina-mojave-or-high-sierra-full-installers/. Upgrade to High Sierra once you have it installed. This page also has links for Lion in case you really want Lion. All the links are to Apple downloads - so nothing dodgy from Mr.Macintosh.

Most often I use Mist to download installers from Apple.

i have found it,s a imac 9.1 core 2 duo 2.2. I have managed to install el capitain and upgraded with an old ddr3 4gb stick which made a big difference. I have installed open core 2.2 and hope to install catalina.. Hopefully it will be fit for purpose control a digi 003 and watch youtube videos
