Hello everyone, i am on a lenovo y50 uhd. it came with windows 8.1, and i upgraded it to 10. however, i really didn't feel liking both 8.1 or 10, however, so i went ahead and tried to install windows 7 professional 64bit as a dual boot. i made sure in the bios:
1-Secure booting is disabled
2-OS Optimized default is disabled
3- Legacy support is enabled (With UEFI as first)
So. after that i went straight into booting from the usb. everything went fine until i came to the partition selection. i selected the new partition i made for windows 7. but got that error that it can't be installed because it's a type of GPT. i did some research for the problem and it seems that one of the fixes was to convert to MBR, (Which i couldn't because i had 5 partitions 2 of them are for recovery purposes, etc..). and i can't use the CMD method because that will delete everything.
now a friend of mine was able to install it without any problems. with same bios settings to mine.
What can i do to fix this? by the way the usb is Toshiba 64GB. (and 2.0 i think).
