my win not booting

[ravi teja_1]

i installed win 8.1 on my acer e5-551g using youtube tutorial
i cleared my hdd partion as shown in video and installed win 8 all fine.
my lap then showed only 100gb(i set that value as shown in video)
so i dicided to again reinstall
followed same procedures this time again but the finsh/next symbol never activated
i decided to stop the installing process
when i turned on my comp it is showin os not found and i cant reboot on usb and hhd too

you can't boot to the hdd because you wiped it clean long before you pressed cancel.
take the usb out, unplug the battery, hold down the power button for 10 seconds. then boot to the usb drive again and try to install windows again.

it doesn't matter how many gig's you give the installation (as long as you give it more than 32gbs) because you can always expand the os partition after its done installing
