My stupidity with other OS's

Hey guys, kinda new here, I know a little bit about computers but not a lot... I was experimenting with some other OS's (Ubuntu, Fedora, WinXP, etc.) and I decided just to keep 7 for now and delete the rest. Well, all the OS's came off fine, I reinstalled 7 with no problem, I just have one thing that's annoying me... it still doesn't just boot 7 automatically, it asks if I want to boot Win7 or "an older version of Windows". Of course, whenever you click it it just basically says nothing is there, because there is nothing there... I just want to know if anyone knows how to remove this option so Win7 just boots without any other options. I know it's probably impossible to remove it COMPLETELY, so even if there is just a configuration in Win7 that just boots Win7 without asking to boot any other OS's but doesn't delete your old OS's, that'd be fine. Any help would be appreciated, I'd just like to get rid of the "older Windows" option lol.

Type "msconfig.exe" into the start search and run the program presented

One the Boot tab of the application you should see the two start-up choices you are seeing

simply select and delete the entry you do not need

I've actually used msconfig already, but all that shows up is Win7. I used that to delete a previous 3rd option, a dead link to a second Win7 (I still don't fully understand what happened there). I've done the disc clean up and disk clean up and disk defragment but nothings worked, I'm at a loss :'(

Alright, I screenshotted, it's just the reserve and c:/ right now evidently :/

Does anyone else think they could have any idea what this might be? Sorry for self bumping here.

Looks like you still have linux code left over.
All Linux code must be deleted.As you have had linux on the HD you need do a Clean all & full format.
Disk - Clean and Clean All with Diskpart Command
Partition or Volume - Delete
Partition or Volume - Create New
Partition - Mark as Active
Try a full clean & full format in command prompt.
1) Boot DVD & Press Shift+F10 (for command prompt)
2) Boot DVD, & Command Prompt at Startup
(for command prompt)

Type in command line
DISKPART
LIST DISK
SELECT DISK # (win HD)
CLEAN ALL
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT fs=NTFS
ASSIGN
EXIT
EXIT
