After trying to install both OS during 2 days, I'm confused and getting mad…
I have SSD 128 GB and HDD 500 GB both empty. My laptop is Asus K55VM. BIOS support UEFI.
What I have done:
Install new SSD (Samsung 830 128GB)
Use GParted on liveCD to create new table of partitions (GPT) and create 3 partitions (in the SSD) for different purposes:
- Partition 1: 80 GB (w7);
- Partition 2: 30 GB (Ubuntu 12.04 -Just / -);
- Partition 3: 10 GB unused (for future extesion of the other partitions)
Install Windows 7 (with UEFI) in Partition 1. This create:
- /dev/sda1 -> 100 MB for System (UEFI boot I guess) – FAT32
- /dev/sda2 -> 100 MB aprox. for MSR
- /dev/sda3 -> 79.800 MB aprox. for Windows7 data
In this point everything works fine. I have W7. Now I install Ubuntu 12.04 amd64 (with UEFI) as follows:
Install / in Partition 2 -> /dev/sda4 30 GB ext4, and in the hdd I install /home and swap.
I select bootloader in /dev/sda1 (where it's supposed to be the UEFI boot).
I install updates and reboot.
Problem: Now just appears grub menu with Ubuntu entries and not Windows 7.
Alternative solution found: When I turn on laptop, before loading GRUB I press ESC key and appear BIOS boot, so I can select to boot the Windows partition, Ubuntu partition, DVD, USB, etc… but I think is not the best way to boot different OS.
I've tried: sudo update-grub2 with no success.
What can I do??
