I am now facing a problem in installing Ubuntu 12.04 LTS alongside windows 7. First of all, here is my pc configuration:
- Intel desktop board DB75EN,
- Intel i-5 3450 processor,
- 1 TB Western Digital Hard disk,
- 6 GB ram,
- nvidia 8400gs graphics card.
Firstly I was able to make a dual boot system. But there was a problem in my motherboard with the on board graphics. So I get back to Intel and they replace it in 12 days. Now I have to do a fresh installation. Now I first install Windows 7. When I am going to install Ubuntu 12.04, the "Install Ubuntu alongside Windows 7" option was not there.Then I go with the "Try Ubuntu" option. While opening Gparted, it shows a 1TB unallocated space in the hard disk.
I format again the whole hard drive and make new partition table with Windows 7 bootable USB drive and leave a 200Gb unallocated space. But it failed with the same option. It failed recognize the previously installed Windows 7.
I search the forum...
I ran the command:
sudo parted -l
And I get the following output:
Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No? y Model: ATA WDC WD10EZEX-22B (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags Model: hp v112b (scsi) Disk /dev/sdb: 8047MB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 31.7kB 8046MB 8046MB primary fat32 boot, lba
What should I do?
