Win7, Ubuntu dual system, encounter partition is not available problem, and uninstall Ubuntu after Win7 can not open the machine

Profile:

Last night is still intended to physically install Ubuntu, with virtual machine is really some cards, after all, is virtual out, there are so many programs to allow, low efficiency is understandable. After the physical installation, Ubuntu display is better, the picture is clearer, and windows, should not say that some places have.

Online search of a Win7,ubuntu installation tutorial, http://jingyan.baidu.com/article/60ccbceb18624464cab197ea.html (may wish to become "tutorial a" for the following description), Basically are correct, a few small details I in the following article to fix it, the veteran will not spit groove, this is for the novice to see. Thanks for the contribution of the author of tutorial A, it really helped a lot of people, thank you.

Ubuntu installation than Windows installation is also simple, want to install XP, Server 2003,win 7, it is a step by step, grid, partition, Ghost, and so on step by step to explore and learn their own time spent.

Restore Windows Ghost Image after waiting for Windows installation (half an hour), but also to drive (the package driver is not necessarily appropriate), patching (especially the very old Gho image, Patch hit you for a few hours); time is really long. And Ubuntu is really convenient ah, a stop, the above all the flow of words on the half-hour less than to fix. The premise is that you have to master the installation process, and some of the common problems of the solution, if you encounter a problem, it is just Windows or Linux will take time. It reminds me of the first time I gave two girls a Win7 64bit flagship system, and a 64-bit, that GPT and MBR file format problem really made my egg ache, then did not understand the relationship and the difference between this, with a win7-64 CD-ROM, a smooth fix, a set of my back and forth a few hours , did not fix, finally ghost has an image up to be done, the real egg hurts ...

Words back to the point, I follow the steps of tutorial A, step by step, in the Ubuntu partition encountered an "not available" problem, check the data know: most of the machine or MBR file format, do not know what the MBR is to Baidu a bit, than I said clear, in short, is a disk partition management format. MBR restricts the primary partition to more than 4, and the extended partition is a primary partition, unlike the normal primary partition: The extended partition can continue to separate several logical partitions. A Windows computer that occupies at least two primary partitions: the C drive and the extended partition.

So the Ubuntu partition may not be available, so if you do not have a "partition not available" issue during the installation process, it is recommended that you follow the 4 partitions described in tutorial a above:

/primary partition, swap,/boot,/home logical partition.

If you have a "Partition not available" issue during the installation process, a simple and effective workaround:

A, please check and make sure that the number of primary partitions under win <=4

B, set/also logical partition, swap,/boot,/home logical partition unchanged, so it's OK. Ubuntu works in dual-system situations. For Ubuntu single system is not possible, because a disk must have a primary partition, but if you are a single system will not have this problem.

In addition to the first step of tutorial A to organize the unallocated disk space for Ubuntu use, the tutorial with the Win7 of the sub-disk tool I do not use, I am using the old Peaches PE-disc doctor completed, the following article introduce it.

Article Order:

0. Install the Win7 first, then the Ubuntu.

1. Use the old Peaches PE-disk doctor to finish sorting out unallocated disk space for Ubuntu.

Workaround for partition unavailable problem during 2.ubuntu installation

3. Booting windows with Ubuntu, after uninstalling Ubuntu, may cause Windows not to start the solution.

0. Install the Win7 first, then the Ubuntu.

After all, most people are familiar with windows in the familiar with Linux, and the online tutorials are recommended to install Win7 and then install Ubuntu, there should be a reason, but I do not want to go to the bottom, can smoothly and conveniently installed on the good, to put our time and energy on the steel blade.

1. Use the old Peaches PE-disk doctor to finish sorting out unallocated disk space for Ubuntu.

Tutorial A is the first step to sort out unallocated disk space for Ubuntu use, the tutorial with Win7 's own sub-disk tool I do not use, I am using the old Peaches PE-disk doctor completed.

Old Peaches PE tool is a very useful system maintenance software, I like it, it has a lot of convenient and powerful features, there is time for beginners can use, Old Peaches official website has a complete use of the tutorial, simple and easy to apply.

http://www.laomaotao.net/Old Peaches official website. Usage See Help http://www.laomaotao.net/help/

First use the old peaches to make a U disk Startup disk, restart the computer, set to boot from the USB stick USB-HDD mode. This step for beginners a bit difficult, because different computer startup USB settings slightly different, just contact is not easy to find, can be Baidu a bit. My desktop has a shortcut boot menu, restart when you press F12 to enter, optional "USB-HDD" the first startup item, single-time valid. My notebook Asus, reboot press F2 to enter BIOS board settings, boot menu, set first boot item, or in the last large column of navigation (like Save & Exit Column), select your USB flash drive, one time valid.

Access to the PE system, with the Disk Doctor graphical interface operation to delete a partition is very simple, I cut a map can be the matter, I put the original win under the last plate F plate All to Ubuntu use, the accompanying drawings are as follows.

Warm reminder: The data is priceless, please back up the data before operation, the operation will delete all the data of the F drive.

Words back to the point, I follow the steps of tutorial A, step by step, in the Ubuntu partition encountered an "not available" problem, check the data know: most of the machine or MBR file format, do not know what the MBR is to Baidu a bit, than I said clear, in short, is a disk partition management format.

Resources:

Go to Baidu yourself the difference between logical partition and primary partition.

There should be too many primary partitions for your win7 partition, and second,Ubuntu partitions are mounted on logical partitions . My Computer XP,Win7,ubuntu three system. No problem.

3. Booting windows with Ubuntu, after uninstalling Ubuntu, may cause Windows not to start the solution.

This is also a concern in tutorial A, an old bird told me that this problem, with the PE tool to repair the Windows boot file can be, most of the PE is integrated with this tool, older peaches PE also has.

So after the novice himself familiar with the PE, he can solve a lot of problems, this is good.
