I was using Windows 7.
Later, using USB bootable Ubuntu I installed Ubuntu on newly created NEW PARTITION TABLE.
Ext4 format. sda1 - Ubuntu / sda2 - Swap base sda3 - Logical drive /data sd4 - Logical drive /backup
After installation is complete, when I remove my USB drive and restart the machine.
I see this error on Boot screen.
Intel UNDI PXE 2.0
Check cable connection!
After that screen, it shows me F12 menu, if I select any of them same thing again.
But if I try to install Ubuntu again,it works. But after installation same issue again.
I have now converted my HDD to MBR with Partition Wizard Bootable USB. Problem persists, even after installing again.
My Laptop specs:
Intel 4000HD gfx
