Create a bootable CD or DVD with or without floppy

With the CD-ROM available on almost every computer nowaday, floppy drives become a history. However, for those who find computers a hobby, might run into a situation when they need to create a bootable CD that works just like the old floppy disk. Unfortunately, to do this, you still need a floppy drive to read your bootup floppy disk. Wait, the good news is, you can just down load a bootable ISO image and burn it to a CD. And even better, we have a copy of an ISO image right. You can download this image and follow the instructions below, or you can do a web search for more options.

The information on this article will guide you step-by-step how to create a bootable CD/DVD, either using a bootup floppy disk or a boot image file. You will end up having a bootable CD or DVD, with CD-ROM driver supported, that could startup your PC and bring up the command prompt. This is going to be a good starting point, then you can run other utilities such as hard drive ghost, etc..
Many current CD/DVD burning software support the bootable feature. If you already have your favorite burning software, look around to find the bootable option. For this article, I will use the steps and sample screen-shots with the burning tool called Nero.
You will need a boot disk (floppy) or a bootable ISO image to start. If you don't have one, you can download an ISO image . This boot image is Windows-98 based, which means it uses the Windows 98 bootup sequence, which should do what we need. You can also download different boot disk images from the internet. I've found bootdisk.com has a very good collection.
I assume that you already have Nero installed. Also, it is highly recommended to use a rewritable disc so you can redo the process if you have to.

  1. Launch Nero Burning ROM
  2. At the New Compilation Window, select "CD" from the drop-down menu and select "CD-ROM (Boot)" for CD, (or select "DVD" and "DVD-ROM (Boot)" for DVD)
  3. If you use a bootup floppy disk, insert the floppy disk and select "Bootable logical drive..."
  4. If you use an image file, select "Image File" then click "Browse" to browse to the image.




    At the "Open" Window, browse to the location where you saved the boot image and choose the image you wish to use and click "Open" (you might need to change the "Files of type" to "All Files" in order to see files with different extensions.)
  5. Click "New" at the New Compilation Window.
  6. Nero New Compilation Window disappears and Nero brings up its main screen where you can add more files to the CD/DVD if you wish. For example, adding a "ghost" folder with the file "ghost.exe" as follows.
    Once you're done adding all the files you wish to, click on the "Burn" icon.
  7. At the "Burn Compilation" Window, select "Burn"!

(CrossOver Linux) Windows Applications, Seamlessly Integrated On Linux

CrossOver Linux allows you to install many popular Windows productivity applications, plugins and games in Linux, without needing a Microsoft Operating System license. CrossOver includes an easy to use, single click interface, which makes installing a Windows application simple and fast. Once installed, your application integrate seamlessly with your Gnome or KDE environment. Just click and run your application, exactly as you would in Windows, but with the full freedom of Linux.
CrossOver Linux lets you use many Windows plugins directly from your Linux browser. Plugins work on any x86 based Linux distribution and will integrate with most browsers including Firefox 1.x, Netscape 6.x, Konqueror, Mozilla, and Opera. CrossOver also integrates with Gnome and KDE to let you transparently open any Word, Excel or PowerPoint file. But even better, you can open these attachment types directly from any mail client.


One Application: Two Delicious Flavors!


We’ve created two versions of CrossOver Linux — Standard and Professional — to serve our home-user/enthusiast and corporate markets even better. CrossOver Linux Standard provides individual users with the ability to run a wide variety of Windows software cleanly and economically. CrossOver Linux Professional provides corporate users with the enhanced deployability and manageability features their environments demand.

Offline Windows Password & Registry Editor, Bootdisk / CD

I've put together a single floppy or CD / USB Drive which contains things needed to reset the passwords on most systems. The CD can also be installed on a USB drive, see readme.txt on the CD.
The bootdisk should support most of the more usual disk controllers, and it should auto-load most of them. Both PS/2 and USB keyboard supported.
More or less tested from NT3.5 up to Windows 7, including the server versions like 2003 and 2008. Also 64 bit windows supported.
DANGER WILL ROBINSON!
If password is reset on users that have EFS encrypted files, and the system is XP or newer, all encrypted files for that user will be UNREADABLE! and cannot be recovered unless you remember the old password again
If you don't know if you have encrypted files or not, you most likely don't have them. (except maybe on corporate systems)

Windows Tricks : Changing Startup and Log-off screens

Startup Screen
  1. Create a 320x400 bitmap in the root directory and name it LOGO.SYS
  2. You can use LOGOW.SYS file in the Windows directory as a starter
Logoff Screens
  1. There are many system file that constitutes Lofoff screen.
  2. They are actually bitmaps 320x400 that just have a different extension
  3. The hidden file in the root directory LOGO.SYS is the startup logo.
  4. There are two files in the Windows directory.
  5. LOGOW.SYS is the Wait while Shutting down ... screen.
  6. LOGOS.SYS is the You may now shut-off or Reboot screen.

AUTO DELETE TEMPORARY FOLDER.!!


ll what i prefer is %temp% " without quotes.. at Start -> Run.. this opens ur temp folder n den u cal erase it neatly// still try dis one too..

First go into gpedit.msc Next select -> Computer Configuration/Administrative Templates/Windows Components/Terminal Services/Temporary Folder Then right click "Do Not Delete Temp Folder Upon Exit" Go to properties and hit disable. Now next time Windows puts a temp file in that folder it will automatically delete it when its done! Note from Forum Admin: Remember, GPEDIT (Group Policy Editor) is only available in XP Pro.



CD ROM STOPS AUTOPLAYING/AUTORUN.!!

And the AutoPlay Tab has disappeared in My Computer, Devices With Removable Storage, Right Click on CDROM, Properties.
Solution: The service: "Shell Hardware Detection" has been set to Manual or Disabled. Go to Control Panel, Administrative Tools, Services. Return this service to "Automatic
".

CLICKING * .AVI FILES ON EXPLORER CAUSING 100% CPU USAGE.!!

Well windows seem to have a REALLY big problem when it comes to reading AVI files. It seems that when you click on an AVI file in explorer, it'll try to read the entire AVI file to determine the width,height, etc. of the AVI file (this is displayed in the Properties window). Now the problem with Windows is that if you have a broken/not fully downloaded AVI file that doesnt contain this info, Windows will scan the entire AVI file trying to figure out all these properties which in the process will probably cause 100% CPU usage and heavy memory usage. To solve this problem all you have to do is the following:
1. Open up regedit
2. Goto HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler
3. Delete the "Default" value which should be "{87D62D94-71B3-4b9a-9489-5FE6850DC73E}"
Voila! Please not that this will no longer provide you with the windows properties displaying the AVI file information such as width, height, bitrate etc. But its a small price to pay for saving you resources.
NOTE: Please use caution when using regedit. Improper usage may cause windows to behave imcorrectly. Also, I cannot be held resposible. Backup your registry first.

To get back the username and the picture, reverse the above procedure.

For the New Start Menu, Windows XP looks for the <username>.bmp file in the folder

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures

If the file is not found, it takes a picture from the "Default Pictures" sub-folder. By renaming the <username>.bmp and the "Default Pictures" folder, you're giving no chance for Windows to fetch an image for the Start Menu

A "secret" about Barcodes

Did you ever wondered what barcodes mean?
I 'll not say much.
The most common barcode systems are two. EAN and UPC.
EAN meaning European Article Numbering System and is used in most countries including all Europe countries and other.
UPC stands for Universal Product Code and is used in USA and Canada.


This is a EAN bar code which i don't know if it's in use or no but it's okay to tell what I want.
As you noticed it has black and white lines and also some numbers.
The lines are read by machines called Bar Code Readers. But numbers can be read by anyone.
What do these numbers mean?
The meaning is very simple.
#0 and #1 show the product origin and the number coding system of the barcode.
#2 - #6 are the Manufacturer code
#7 - #12 are the product code
#13 is the checksum. It is used to check if the other number were read right. How is it calculate?
To calculate it you simply calculate the sum of even placed numbers (let's say it A) and the odd placed numbers (let's say it B).
Then you find C = A + 3 * B.
The #13 number is the number which you add to C that (C+#13)/10 = 0.
Actually is C%10 (modulo).

Please post any comments.

Remove the Username and picture from Windows XP New Start Menu

 The User account picture can be removed by turning off the Welcome Screen. Or, by switching to Windows Classic theme. Follow the method described in this article if you want to remove the username and picture from the Start Menu, without disabling the Welcome Screen and Windows XP Theme.

For those who want to remove the user name and user account picture from Start Menu, in order to have a blank blue panel at the top, try this:

( For example, if your username is Robert, rename Robert.bmp to old_Robert.bmp )
Next, rename the following folder:

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\Default Pictures

Also make sure that acrobat reader is not open else it will lock the files and not allow you to move the files).

SPEED UP MENU DISPLAY.!!

When using the start menu the you will notice a delay between different tiers of the menu hierarchy. For the fastest computer experience possible I recommend changing this value to zero. This will allow the different tiers to appear instantly.

Start Regedit. If you are unfamiliar with regedit please refer to our FAQ on how to get started.

Navigate to HKEY_CURRENT_USER\Control Panel\Desktop
Select MenuShowDelay from the list on the right.

Right on it and select Modify.
Change the value to 0.
Reboot your computer.

To get back the username and the picture, reverse the above procedure.

 For the New Start Menu, Windows XP looks for the <username>.bmp file in the folder

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures

If the file is not found, it takes a picture from the "Default Pictures" sub-folder. By renaming the <username>.bmp and the "Default Pictures" folder, you're giving no chance for Windows to fetch an image for the Start Menu
