[windows 7] unauthorized changes on the firmware, operating system, or UEFI drivers

Problem
A friend called me last week that he has a problem with his PC. He has Windows 7 and after installing some updates, the system couldn’t reboot. He got the following error message:

(Screenshot from here.)

Solution
I found the solution here. In a nutshell: enter BIOS -> Boot -> Secure Boot. Next to “OS Type” you must have Windows. Change it to “Other OS”. Save and reboot.

simplescreenrecorder

September 24, 2017 Leave a comment

Problem
Under Linux you want to do some screen capturing. For instance, you want to do some tutorial videos.

Solution
I used gtk-RecordMyDesktop for a long time, but my current favorite is simplescreenrecorder. With gtk-RecordMyDesktop I could only save in .ogv format that I had to convert to .mp4 with ffmpeg. simplescreenrecorder can save directly in mp4 format.

Adobe Premiere Pro CS6
For editing my videos, I started to use Adobe Premiere Pro CS6. First, I asked my friends, and most of them suggested this. Second, I found some good and detailed tutorial videos for this software. I’m a newbie in video editing, so I needed some tutorials that showed everything step by step.

However, in Premiere Pro I ran into a problem. You need to import a video file and pull it to the timeline if you want to edit it. However, when I pulled an mp4 file, the audio track didn’t appear on the timeline. I had a workaround solution: from my .mp4 I extracted the audio in .wav format (with ffmpeg), and pulled it to the audio track. Strangely, the audio track was often a little bit shorter than the video track. But it was just annoying, it didn’t cause a problem.

So I tried some other screen capturing tools next to gtk-RecordMyDesktop, and that’s how I found simplescreenrecorder. After several trial and errors, I figured out why the audio track was missing. Whether the audio track appears or not depends on the audio codec! If you save the audio in AAC format, then Premiere Pro will like it and the audio track will appear when you pull such an .mp4 on the timeline. The good news is that you can select in simplescreenrecorder what audio codec you want to use!

Screenshots
Here are some screenshots of my simplescreenrecorder setup:

Pale Moon: an extremely fast web browser

April 16, 2017 Leave a comment

Pale Moon is an open source web browser, based on Firefox. It’s available for Linux and Windows too. Pale Moon focuses on efficiency and ease of use.

Pale Moon is surprisingly fast. It won’t replace my primary browser (which is Firefox), but I’ll use it for some specific sites.

Create a Windows installer USB stick from an ISO under Linux

September 30, 2016 Leave a comment

Problem
I decided to try Windows 10 and install it on a laptop of mine (worry not, it’ll be dual boot :)). Having an ISO, how to put it on a USB stick? In addition, Windows should install itself from the stick…

Solution
The software winusb did the job. Its usage is clear and simple:

$ winusb
Warning: you should run this script as root !
Error: No install method specified !

winusb usage
Install a windows ISO on an NTFS partition and edit MBR of the device
  winusb --install <iso path> <partition>
  Example: winusb win7_amd64.iso /dev/sdd1

Completely format a drive and install the ISO on it
  winusb --format <iso path> <device>
  Example: winusb win7_amd64.iso /dev/sdd

Options
 --verbose, -v        Verbose mode
 --help, -h           Show this help message and exit
 --noColor            Disable color

I had an empty USB stick with an NTFS partition, so I chose the “--install” method. The preparation of the USB stick is long, it took 15 minutes. Sometimes I had the impression that it got frozen but then it continued. So don’t worry, give it some time to finish.

Tip from here.

installing EasyPHP

June 27, 2016 Leave a comment

Problem
I wanted to contribute to a PHP project but under Manjaro I couldn’t test it locally. I got a “Fatal error: Call to undefined function curl_init()” message that I didn’t manage to resolve, though the line “extension=curl.so” was present in my php.ini :(

Solution
After a few hours of trial and error, I decided to develop this project under Windows. I have Windows in VirtualBox, I put the PHP project in a shared folder, so my idea was to edit the source under Linux and visualize the result under Windows.

I chose EasyPHP and installed the latest EasyPHP Devserver that provides a complete development environment.

When I opened the project I got the same error since curl was not enabled by default. On the dashboard I could edit the php.ini file and uncommented the line “extension=php_curl.dll“. However, after restarting the webserver I got another error: libssh2 is missing. I found the solution here (ken’s comment):

"I had to also also copy libssh2.dll into my Apache24 folder 
for this to work with my PHP 5.6.2 installation. So altogether 
I had to do the following:

Move to Windows\system32 folder:
libssh2.dll, php_curl.dll, ssleay32.dll, libeay32.dll

Move to Apache24\bin folder
libssh2.dll

Uncomment extension=php_curl.dll"

I found all these files in the install folder of EasyPHP. There are two versions of each, one in a “…vc11…” folder, while the other one in a “…vc14…” folder. I worked under PHP 5.6 so I copied the vc11 versions of each file mentioned above.

After this Apache restarted without any error.

Linux: install Windows fonts

June 24, 2016 Leave a comment

Problem
I wanted to create a meme image manually in Gimp but I didn’t have the required font (Impact). What now?

Solution
The remedy is here: https://wiki.archlinux.org/index.php/Microsoft_fonts. I have a dual boot machine with Windows and Linux, so I decided to put a link on Windows’ Fonts folder (I didn’t want to copy 550+ MB fonts).

# ln -s /mnt/Windows/Fonts /usr/share/fonts/WindowsFonts
# fc-cache

The prompt “#” means a root shell. Restart Gimp and the Windows fonts will be available.

How to update Windows 7 SP1

June 13, 2016 Leave a comment

Problem
A friend of mine asked me to install Windows 7 on his laptop. I installed Windows 7 SP1, but something changed because when I tried to search for updates, it didn’t want to finish! I waited for 12 hours but it was still looking for… Damn, how to do an update?

Solution
Download manually these updates: KB3050265, KB3102810, and KB3125574 (this last one is a big one, a convenience rollup update). Do the following with each update:

  • Start an admin terminal and stop the Windows Update service: “net stop wuauserv”.
  • Install the update. Restart the machine if you are asked to.
  • Take the next update and repeat.

There is no need to restart the WU service manually since it is started automatically after a reboot.

When these three updates are installed, the Windows Update will find the updates “quickly” (“quicly” is relative; for me it was about 15 minutes).
