I am trying to do clean installation of windows 10 on my dell Inspiron 15 5558 laptop. However, during partition formatting step, windows 10 setup stuck and do not proceed. If I do not select the disk format step and move with windows installation then it windows setup in "file copying" step.
I am using usb as installation media and booting it in UEFI mode.
I tried with secure boot option enable/disable and did not see any difference. I have tried two different bios version "A09" and "A13" and experienced the same problem .
I have feeling that something in firmware is preventing windows setup to modify the drive where I want to install the clean copy of windows. I have tried the installation in so many configuration and did not work. I tried to boot the usb in legacy mode but later during installation step, setup complains that drive has GPT configuration and cannot continue with installation.
Somehow, I cannot restore the computer to factory settings because I upgraded to windows 10 and did not create the recovery disk.
I would like to know that did anyone already experience this kind of problem. How can I approach the dell because my warranty expired 2 months back.
Any suggestion would be highly appreciated.
Best Regards
AC
