Increasing hard disk space (vdi) size of a VirtualBox guest VM

I had to create a VM for searching some 6TB (that is 3 years of mails for 800 users) of mails from a NAS storage. I installed VirtualBox on a desktop with Linux Mint 19 with 16GB RAM and 1TB HDD. Then created a VM for Windows 7 with default configuration. The size was only 32GB which was much less than what was needed. I couldn't spare much time as the search request was very urgent. After a 3 week search ordeal the Windows 7 guest OS crashed which made me search for VDI resizing in DuckDuckGo. I got the below command from ASKUBUNTU.

VBoxManage modifyhd YOUR_HARD_DISK.vdi --resize SIZE_IN_MB

I wanted 100Gb so I converted it in DuckDuckGo with command 100 GB to MB and it gave 100000. So the command I derived is as below.

VBoxManage modifyhd /home/rhs/VirtualBox\ VMs/Windows7/Windows7.vdi --resize 100000

It gave the result/output as below if the command is correct.


When I started the VM Guest Windows 7 OS I found the HDD space was only 32GB still.

So something struck me like I saw in the disk resize option in Windows 7. So I headed to the Control Panel > Administrative Tools > Computer Management > Disk Management option and saw that 60GB odd was left as unpartitioned space. So I right clicked on C Drive and saw extend option. The extend option gave me the full available space. Click Next two times and viola the total 100000MB was converted to 99GB.

By the way I restarted the VirtualBox before the Guest OS resize.

Problem solved

As a citizen of India we should cast vote in this 2014 election. There is option for NOTA in this election so your vote is much more powerful. We should teach our corrupt politicians by electing a person who has done good for his locality and not on party or religion. A party or religion will not bring our society to the top but we being good citizens and good humans can make it happen.

Google Nexus 4 upgrade to Android 4.3 Jelly Bean

Ever since last Wednesday (24 July 2013) when I got the information that the Android 4.3 will come to my Nexus 4 and Nexus 7 I was trying the update and nothing came through. That why I toady searched and found the below procedure from Internet. So after several tries I went through the 6th step which nobody had mentioned the update came through. Happy to see me using the latest Android which is 4.3 on my Nexus 4. When I reach home today I will try this procedure on my Nexus 7 3G 32GB and update you all.

1. Go to Settings -> Apps -> All

2. Find Google Services Framework.

3. Tap on Force Stop.

4. Select Clear Data.

5. Once cleared data it will ask for location settings confirmation. Select confirm.

6. Shutdown and restart the device. (most of the people who have mentioned this procedure didn't mention this part. Only because I did this part the update worked)

7. Head back to the Settings, go to About, and check for a System Update. (you can see that your last update checked date as 1/1/1970)

Most probably the update will be found and will be downloaded and upgraded. Please let me know by comments below if you had this procedure worked.

Thanks all of you who have posted this procedure on the net.
