Windows 10 not in MSCONFIG boot menu

Hi,
So I was dual booting windows 7 and 10, and when I go into msconfig it used to always shows 7 and 10 in the boot menu.

I deleted my windows 7 partition and wanted to make sure windows 10 is set to default OS, but now it shows nothing in the boot menu.


I'm to scared to turn off my PC incase it wont boot :P

Your boot files were on your Windows 7 partition, so now you don't have any. I would recommend installing Macrium Reflect Free, creating a Rescue USB/DVD, and booting from that to create the boot files on your Windows 10 partition.

Or you can do this - just substitution Windows 10 for Windows 7:

I've already mucked up as now it says MTLDR is missing.

Press crtl alt del.

I don't have any OS at the moment :/

Looks like you may be facing a clean install.
Got any bootable media?

Yep, but no idea how to merge partition into one.

If you're going to go ahead with a clean, ('bare metal'), install, boot from your install media, follow the prompts and choose 'Custom Install'; at the 'Disks' window delete desired partitions and 'Extend' them into one, then click next and follow the normal install procedure.
Before you do, make sure you've exhausted all your options first and make backups of anything you can!

Well all my content is stored on a HDD as I use a SSD for OS.
so I'm happy with a clean install.

Does everything else look alright.

You still have all of the OS, but like I said, the boot files were on the partition you deleted. You can rebuild the boot files by booting from a Windows 10 installation USB/DVD.

@ Mitchell:

Try the other guys suggestions and try repairing the boot loader first.
If you've got data somewhere in there, may not want to lose it.
