How to format a previous system drive into one partition?

I'm on Windows 11 and I was to use my old Windows 10 start up disk as a storage drive, but don't know how I can format it as one partition.  Currently it has three partitions:  System Reserved, Recovery and Storage.  Could anyone please tell me how I can do this?  Thank you!

When I right click on the partitions, the only one that lets me do anything is storage partition.  How can delete the other two? Thanks! Update:  Oh wait I did get as far as getting rid of the system reserved, but the Recovery partition offers no options.

Thank you, Pkshadow, I seem to be getting somewhere now, but I still haven't been able to combine the unallocated space with the other partition.  I'll keep trying...  OK, I was able to format the one of them into one partition!  Thank you so much! 
Now, on another drive (I'm trying to format another old system disk as well), I still can't do anything with the Recovery volume. When I right click on it, I just get "Help" with takes me to a page about the Disk Management in general.

Hi, well instead of beating head against the wall this is totally free (used on and off for years) https://www.paragon-software.com/free/pm-express/#

There should be able to merge or delete the partitions.

will work.

Thank you, Pkshadow, I'll check that out... And thank you, OldsOd!  I was just reading that online as well and was just about to try it!

Think we are thinking along the same lines : https://www.techtarget.com/searchwindowsserver/tip/Using-Diskpart-to-create-extend-or-delete-a-disk-partition

I went ahead and used Diskpart and it worked perfectly! Thanks everyone!!!  I appreciate all the kind help!

Great news, thanks for letting us know

You are welcome, kalibahlu.

• Backup all important data.
• Access Disk Management through the Start menu or Win + X shortcut.
• Delete existing partitions on the disk.
• Create a new partition in the unallocated space.
• Format the new partition with NTFS file system. Always double-check before formatting to avoid data loss.

Thanks! I already solved the problem with DiskPart, but I appreciate your reply. What you described worked for the System Reserved partition, but for the Recovery partition, I had to use DiskPart.
