Installation doesn't detect Windows 7
Go to the option 'Something else' .you'll get the partition table.Select the partition you want to install.
Then set the filetype to ext4.Select the format checkbox.Select root '/' as mount point.
Next before installation go to "device for boot loader installation"(see the image) and select the partition you've created just before.then press 'install now'.
After booting with live usb/cd ,Run following command in terminal,
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
provided: boot repair
I hope this will help.

My laptop came with Ubuntu. I removed it to install Windows 7 64-bit. I don't remember if I did anything special, I just formatted the entire hard drive. Now I am trying to install Ubuntu 13.10 alongside Windows, but the Ubuntu installer says:
This computer currently has no detected operating system and gives me 4 options:
• erase disk and install Ubuntu
• encrypt the new Ubuntu.....
• use LVM with ......
• something elseI tried all the solutions I could find.
ran gdisk and for //./partition0 and //./partition1 it shows:mbr:mbr only bsd: not present apm: not present gpt: not present
Computer Management shows 5 partition, 4 NTFS and 1 raw 10GB space which I planned to install Ubuntu on.
c:, raw space and system reserved 100MB are primary partitions, other 2 are logical drive.
Secure boot option is disabled in BIOS and Legacy boot is selected.
Please suggest a way to get the job done.

user248449 about 10 yearsDid that. The installation was completed successfully. But after rebooting when installation completed, I was straight booted in windows 7. No option to go to ubuntu.
