Windows 10: Laptop went into reformat during Microsoft update

I have a Toshiba Satellite laptop with windows 10. about a year ago I started receiving prompts that Microsoft needs to update. These started coming 3 to 4 times a day for about a week and then my computer went into format hard drive and I was unable to stop it. Now all I get when I turn it on is "No bootable device - - Please restart system. What do I do now?

Reformatting Laptop

I'm planning to reformat my laptop and in the Activation tab it says that i have a digital license activated and linked to a microsoft account. My question is if i reformat my laptop would it wipe the Windows 10? I purchased this laptop not knowing if
windows 10 is the default OS or it was installed by the store.

The main reason why i'm reformatting my laptop is because of USB mass storage driver is faulty and no update or installation is fixing it, i even contacted microsoft agents and ASUS agents (my laptop is ASUS x507ubr) and tried all the things they said from
system recovery upto downloading manually of specific drivers. Finally i decided to take it into the local ASUS store so that they could take a look and they said the only way is reformatting a laptop. They suggested that if i know how to do it i should do
it so i wont take extra charges. Hence my question above.

 

Reformat upgraded win10 laptop


Is there a way to know what my license number is? Laptop is not with me at the moment so I could not check it. I believe it still has the sticker where the license is printed at. Does it retain the old license or a new one is made when I upgraded to Win10?

Second question, what would be the best step in reformatting the laptop? Is there an option in Win10 where it would reformat and come back immediately to Win10?

 

Reformat upgraded win10 laptop


Good day!

I have a laptop that started with Windows 8. Then I upgraded to 8.1 then to 10 after the update was offered. However, I hate the bloatware included with the laptop for it takes quite some time for the laptop to be fully functional (normal Asus bloatware + VPN + Spyder calibration software).

I could buy an SSD to make it boot faster but budget does not permit me at the moment. I was thinking I would reformat my laptop to remove the bloatware but the thought of losing my license made me think twice.

What would be the best step to reformat my laptop while maintaining the license? Downgrade to 8 then upgrade to 10 or is there a process to install Win10 immediately?
