Hello, I've recently bought Lenovo y50-70 without OS. It has no cd drive so I did bootable pendrive and installed Windows 7. When I tried to change boot legacy back I didn't see my hdd but only this pendrive (I detached pendrive when Windows was installed and running). However Windows is running normally but booting a little bit too slow for a fresh OS. In My Computer I can see all partitions I did during Windows installation. Can it affect efficiency of my laptop. Should I worry about it? And how shall I fix it?
As far as I understand the issue you are facing:
- You installed an operating system via USB flash drive.
- Your system boots a little bit slow and the HDD is not recognized by BIOS right? This could be related to a hard drive related issue. This is why, it may be a good idea to test the drive.
You say that BIOS detects a flash drive that is no longer plugged in right? That's strange. You can see whether you can set your BIOS to defaults.
