I have try so many time for upgrade it. But never work.
I have try the following
-uninstall the kaspersky (anti-virus)
-clean reinstall windows
-updated all driver, bios
-disable unnecessary hardward (usb,audio )
-uninstall all unnecessary software
Still stuck at copying file 2% (1hour for 1% of copying file, not the bigger %)
I have waited the installation for 7 hours, after that the copying % go to 24, the big % go to 4.
Whole upgrade need a week? I think this is abnormal.
Anyone got the same situation?
