Where is my computer trying to boot from(and how do i fix it)?

I have a laptop, dell inspion 15 series, that has 3 bootable partitions. One is Windows 7 (main), another is Windows Server 2008 R2 (for replicating problems on a server), and windows 7 setup (didnt feel like usb installing).

Currently, the usb ports have nothing other than a mouse plugged in. It had windows 7 for multiple years and server 2008 for just under a year. While i was gone, the computer turned off. When i got back it was trying to boot from what seemed to be a linux thing. I have absolutely 0 linux partitions in my drive and checked again with partition managers. Right after the boot screen it gives this message:

I can type in the "Boot" line.

Can you boot into Windows at all, specifically can you access the Command Prompt using the following method?

Open the Start menu and type cmd in the search box, cmd will appear above the search box in the results, right click on this and select Run as administrator.  This will open the Command Prompt.

When the Command prompt is open type in sfc /scannow, then press Enter.

The sfc /scannow command scans all protected system files and replaces corrupted and incorrect versions with correct Microsoft versions.

If this can't be run you will need a Windows 7 installation disc for the same version of Windows 7 you have installed.  If you have this or can borrow one let me know and I will provide you with a tutorial to access and use the command prompt to run commands from there.

upon booting, it does not open windows boot manager or anything. It goes straight to that. I do not make it to a windows loading screen or anything. It is booting from the hard drive and upon starting, it goes straight to that.

The last part of my post included the question of whether you had the installation disc or could borrow one.  I would like to know the answer to this.

If you don't have a copy of the installation disc you could call your local repair shop and see if they would make a installation disc for your version of Windows 7.  Ex:  Windows 7 home 64-bit.

I usb booted (have the disk right in front of me), shift + f10 and fixed it by repairing the system reserve. Thanks!

Congratulations.  Sounds like you are good to go.
