Updating windows - Microsoft Community

hey everyone,

so have asus k35e laptop came hdd , windows 7. bought adata su800 256gb ssd , installed fine. i've worked on laptops , desktops before, wasn't new me.

i used usb stick install window onto computer, , installation went until system restarted fine. upon restarting screen says "could not complete installation, please restart." common error i've seen littering internet. problem is, can't open command prompt, shift + f10 doesn't work, , neither fn + shift + f10.

asus customer support hung on me , won't me because i'm "upgrading" system , voided warranty , support had through them apparently.

thanks in advance appreciate it! school laptop, desperately need fixed asap

actually, gonna sound weird. selected not automatically authenticate windows , chose option didn't have product key , chose windows 10 pro. went , went install complete put product key in , good!
