65 million + upgrades have been completed so yes, it will load.
Is your Windows 7 up to date, all updates applied?
Here is a list I've been putting together from posts others have made and what they did to get the upgrade to work.
Create an image backpack of your existing operating system to an external USB hard drive using a program like Macrium Reflect Free. If you don't have an external drive, get one as they are relatively cheap. A 1TB drive runs $50 to $60. Create the Rescue Disc before you create the image backup so if anything goes wrong, you can recover in 20 to 30 minutes.
Check for updated drivers for your hardware at the manufacturers web site.
Disconnect everything except mouse, keyboard and display EVERYTHING!
Uninstall your anti-virus if it's other than the built-in Defender.
Uninstall your firewall if it's other than the built-in Firewall.
Uninstall any Start button programs like Classic Shell, Start8, also Window Blinds, etc.
Uninstall any theme modifications.
If you moved any of your user folders to another drive or partition, move them back.

If you upgraded from Windows 8 or 8.1 and used EaseUS Partition Manager to change the partition structure, see Eightblog for instructions on how to get your recovery partitions sorted, because the upgrade won't work otherwise.
Run chkdsk /rand let it start and complete on reboot.
Run sfc /scannowand see if it finds and repairs any system files.
