Install Ubuntu (HDD version) and problems in Win7

I blame myself for the Ubuntu Android Studio, because gfw,gradle always download, with the command line download half of the shutdown, and then I was crippled Ubuntu. and put emphasis on the installation.

In fact, referring to the online post, is a summary, because the system is always bad, and today re-installed Ubuntu, hey, the model becomes worse, by the notes

1. How to install Ubuntu under Win7 (HDD version)

Error 15:file not found is displayed when Win7 hard disk is installed Ubuntu12.04 64-bit.

2. Your own partition information:

The first is to set aside more than 100 g of hard disk space under Win7 and there is no dispatch letter.

/boot Ext4 200M

/Ext4 20G (is root)

/swap Swap partition Unformatted 2G

/Home Ext4 80G (all the rest is given to you and used to store things later)

3. Install backward not to go to Win7, both systems are not going in, stuck in the boot interface and then black screen.

Do not know where I set the wrong, it is said that grub is covered, just as there is a U disk win7 system installation disk, after the point of repair, can have a command line options, and then enter

>bootrec/fixmr

Fixed the MBR, reboot can go in Win7 and Ubuntu selection interface.

Also thought Win7 also to reload, false alarm a.
