I had been booting Win 10, Win 7, Win XP and Ubuntu using EasyBCD 2.3 . I eliminated Win 7 and deleted it's partition merging it with Win 10 on the same physical drive. All of a sudden now when I attempt to boot into Ubuntu, located on another physical drive, all I get is a screen with "GRUB4DOS..Processing the preset-menu" and then nothing. Both Win 10 and Win XP boot normally from the EasyBCD menu. Have tried re-adding a new entry for Ubuntu using GRUB 2 and I get the same GRUB4DOS screen. AutoNeoGrub0.mbr is located in C:\NST along with ntldr for XP. What have I done wrong?
