    Re: Dual boot - Windows 7 & Ubuntu

    I'll be watching this thread with great interest. I wish there's a way to add UEFI to the title since that's the main thing.

    My suspicion is that it is not going to be straightforward. I hope I'm wrong.

    Anyway, all the best.

    Re: Dual-boot - Windows 7 & Ubuntu with UEFI

    There is a lot of difference and many are confused. There also was a bug (one of many) with UEFI and grub that it erased the efi partition, so best to backup the efi partition before installing. Depends on version as supposed fixed in newest.

    UEFI bugs:

    You don't necessarily need to dual boot Windows and Linux on UEFI. Follow the guide http://www.youtube.com/watch?v=PEou2dIcMSE to convert your UEFI to MBR-BIOS without loss of data. Or read about it here: http://commandlinewani.blogspot.com/...sony-vaio.html

    Re: Dual-boot - Windows 7 & Ubuntu with UEFI

    In fact, I have been using Ubuntu since 2005. I had no problems in dual-booting it with windows Vista or Windows 7, whether 32-bit or 64-bit. But when I tried to dual-boot them on my new laptop (Dell Inspiron 15R 5520 core i5) I am stucked with the issue of "UEFI". All my attempts went in vein up till now. I heard Ubuntu is working on solving this problem. I hope it is solved soon!
