Windows Booting Problem

[Enerpi_0016]

Hello everyone! I have a problem formatting my laptop (Sony Vaio VPCEB33FM) I'm using bootable Flash Drive. My laptop is windows 7 Home Premium and I want to format it and upgrade it to windows 10 (I have Windows 10 in my flash drive) I already did the settings at the BIOS (the booting priority) so first the Flash Drive booted and the windows 10 installer shows up and I clicked "Next". Instead of clicking "Install Now", I click the "Repair your Computer" (Bottom Left Corner) because I want to format my laptop. So I've done that.. When I reached the part that saying "Delete all personal data setting ect" I click that and a message pop-up saying that the hard disk is not detected. So I did something that made my PC search for error or something ( I can't remember) so it finished. Then when I booted the flash drive again, instead of showing up the windows 10 installer, it shows the "Windows Boot Manager" Then below you will choose what OS will you use and the only option there is my OS which is the Windows 7 Home Premium. I access again the bios and do the priority boot again ad the same hing happen every time.

Please HELP! what should I do? I cant format my laptop 🙁 Why my Hard Disk cant be detected?)
and why the Windows Boot manager showing up instead of the installer??

THANK YOU FOR YOUR EFFORTS

Sounds like you deleted the data partition but not the recovery partition, that's where/why the win7 boot manager is coming from.

Boot from usb, on the 1st screen go old school Shift+f10 should give a cmd prompt, in there type
diskpart
list disk
{find your drive, assuming 1 drive it should be 0}
select disk 0
clean
list disk
{if drive has * it is selected otherwise select it again}
create partition primary
select partition 1
active
format FS=NTFS label=OS-Drive quick
assign letter=C
exit
reboot to usb

This should give you a drive ready for win10 clean install..

This seems overly complicated, if you want to install Windows 10 and want to Format the drives, why don't you just do a clean install? That will do everything you need.

Follow this guide: https://www.howtogeek.com/224342/how-to-clean-install-windows-10/

Once you're booted into Windows, run a quick backup. If you don't already have a solution, Macrium Reflect or Rollback Rx work great and are free.
