I just bought a new Toshiba Satellite M840 with pre-loaded Windows 8. I checked that Windows is installed in UEFI mode.
I did a lot of research online on how to get Ubuntu 12.10 installed for dual boot.
First, I setup to BIOS as quick boot to normal and disabled the secure boot.
I installed EaseUS Partition Master 9.2.1 and created a 64GB partition (NTFS), I called this partition - F drive.
I also downloaded Ubuntu 12.10 64-bit DVD iso. In Windows 8 desktop mode, I launched Ubuntu Studio 12.10 and installed Ubuntu on this F drive. The installation went all the way without a problem. When the Ubuntu installation was done, I rebooted.
After reboot, the problem appears. I can see a light blue display, showing Windows 8 and Ubuntu. When I selected Ubuntu, it poped up with another screen showing:
Windows fails to start. A recent hardware or software change might be the cause. To fix the problem: 1. Insert your Windows installation disc and restart your computer. 2. Choose your language setting, and then click Next 3. Click Repair your computer. If you do not have this disc, contact your system administrator or computer manufacturer for assistance. File: \ubuntu\winboot\wubildr.mbr status: 0xc000007b Info: The application or operating system couldn't be loaded because a required file is missing or contains errors.
When I power off/on again, if I select Windows 8 (light blue screen, OS selection) the system will still boot up Windows 8 without a problem. The problem is that I am not able to boot into Ubuntu...
Please help! Thanks!
