Uninstall Backtrack 5 Dual Boot Win 7

it’s not uninstall actually, hha just simply delete it.

after a month i tried to use backtrack 5, i found out that my disk space allocated for backtrack 5 was nearly empty, 10 GB was too small. So i’d like to add new disk space, but i haven’t found the way to do it. I came up with uncool steps.

1. Remove old backtrack installation
2. Reinstall backtrack with new disk space allocation

to remove backtrack installation, which is dual booted with windows 7, i have to make sure my windows 7 can still work well. after googling, i got the message to do fixmbr to recover windows 7 boot manager. so here are the steps.

A. Fixing windows 7 boot manager
1. prepare your win7 installation disk (dvd/usb), plug it in.
2. start your computer, set the boot priority from bios setting (first boot usb, or cd/dvd room)
3. when windows 7 installation comes up, choose repair
4. choose repair this computer with recovery tool, click next
5. choose command prompt
6. enter this command

[php]bootRec.exe /fixmbr[/php]

7. reboot your computer

B. Remove backtrack
1. now your computer should start the win 7 automatically
2. go to control panel > System and Security > Administrative Tools > Computer Management > choose Disk Management (under storage properties)
3. u will see clearly your computer partitions, delete your backtrack partition by right click > delete Volume
4. after it is deleted you will have new disk space and u can expand your other windows partition.

partition manager
computer management windows 7

that’s all

when i added new user in my ubuntu hosting and try to access the site, i got the message. i spent some time searching for the problem and solution. my first guess, there is problem with file permission in the home directory. read about unix/linux file permission on my site here.

i use this step to solve the problem.  Continue reading You don’t have permission to access / on this server.

File Permission on UNIX/Linux

in unix/linux sistem it is easy for us to define directory or file permission. there are 3 options : read, write, execute. these options are represented with binary number rwx, respectively for read, write, execute. there are also 3 user type/level exist : user, group, other. user means the specific user logged in the system which is also the owner of the file / directory, group mean several user that has been defined on one group name, and other represent any user exist or the whole world.

each file/directory in unix/linux will be labeled by specific permission, such as drwxrwxrwx. Continue reading File Permission on UNIX/Linux

delete / remove ?wpmp_switcher=desktop

After i use wordpress plugin for mobile web application “WordPress Mobile Pack”  i found that it caused duplicate meta description. Each of my link/permalink will be appended “?wpmp_switcher=desktop”, which indicates that instead of using the web mode display, we will use desktop mode display.

since it created miss configuration to meta description tag, i prefer to remove the plugin. but the affected links seem still the same. trying to understand this thing, i did these 2 things.

1. Clear the dns cache and browser history just to make sure these aren’t the thing that causes the problem.

2. Deleting completely any “WordPress Mobile Pack” in folder wp-include>>themes.

It seems working on my website, u can try to do it with yours too. hope this helpful for you.

One problem that sometimes arises is the web displays the error Establish a database connection, this problem usually occurs because we haven’t started yet our mysql-server program, or already started but not run well. The solution is simply to check whether or not our mysql running and try to run it.
