UPDATE(for those who want to follow this guide or have already followed in past times): Gnu grub shell might appear if you are going to install another linux distribution using wubi, let’s say another version of ubuntu. This is due to the fact that you’ve removed ubuntu but not the wubildr files in the hidden partition(trick to get wubi working on windows, shown later in this article), and they must be updated to perform a new installation…more here https://piergiu.wordpress.com/2012/04/28/wubi-ubuntu-12-04-gnu-grub/
You’ve just installed your brand new ubuntu 10.10, then you reboot, and…
Try (hd0,0): NTFS5: No wubildr
And this for about 1 or 2 minutes! then ubuntu boots up..
The problem is that an hidden partition that windows 7 creates, reserved for the system, about 100mb in size, keeps our loader from ..well.. LOADING our O.S..
How to solve:
- go to “File System”\host\ubuntu\winboot and copy ALL of its content.
- go to (and mount with double-left-click) “System Reserved” and paste ALL you’ve COPIED in step 1.
- then you can reboot and no-more-hanging of our loader, that finally..well..LOADS..
UPDATE: Where does this hidden partition come from? Here’s a pic from the installation process of windows 7!
