In my laptop (Lenovo Ideapad v570), which came with 750GB HDD with 4 NTFS primary partitions I installed ubuntu by following these steps
The 4 partions were, 1.(650GB)Windows7 2. (30GB) Lenovo/Drivers 3.System 210 MB 4. (16GB)Recovery
- I shrunk the windows drive to 245GB, by using disk management in windows 7 and created unallocated free space of ~450GB
- Using ubuntu live cd , I installed ubuntu 11.10 by selecting the option Ïnstall along side windows
Ubuntu 11.10 was installed without any error.
But on reboot, the boot menu does not appear and system boots into Windows 7 . I checked again using ubuntu live cd, and ubuntu is actually installed on the harddrive. (I could browse the files)
The ubuntu disk utility output is as shown below.
As can be seen in the screenshot, there is a warning that says, "Partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested". Does this warning has anything to do with the problem?
