running ubuntu 12.04 64 bit in virtual box
virtual box v4.1 - has provision to run 64 bit guests.
ubuntu 12.04 has been released - so downloaded 64 bit version and tried to install in virual box. had to choose ubuntu 64 bit as type of system to continue. but installation came to a halt stating “enable vt-x/amd-v in bios” .
by default my dell system had turned off virualisation. so i started my system , pressed <F2> , went into advanced bios settings and enabled virtualisation. saved the settings , restarted my system and i was able to continue with installation of ubuntu 12.04 64 bit in virtual box.
host is win 7 64 bit.
not too sure how but with virtual box 4.1.12 and ubuntu 12.04, my mouse can move between ubuntu and windows seamlessly. with ubuntu 10.04 as well as ubuntu 11.10, i had to press the right <ctrl> key to move my mouse from guest to host.
old laptop with a non-working cd drive
how do you install linux on an old laptop which has a failed cd drive and its bios cannot boot from a usb drive.
install plop . download , unzip and run InstallToMBR.bat from the windows directory [laptop was running win-xp. wireless connectivity to the internet was available]
now when laptop is booted, there is option to continue boot from usb drive.
used unetbootin to convert downloaded ubuntu 11.10 iso to usb bootablelinux.
installed ubuntu 11.10 on laptop . except for wireless [broadcom] driver, all other hardware drivers including sound were installed on first install.
updated ubuntu - ran most of the commands given here
now for wireless - simple - just ran -
sudo apt-get install firmware-b43-installer
wireless worked. so did reliance netconnect card.

Making powershell scripts work
powershell on windows 7 does not run unsigned scripts.
run powershell as administrator
Set-ExecutionPolicy RemoteSigned
now we can run powershell scripts which we have created on our own
