I asked for help approx 8 hours ago concerning Invalid Boot.ini. No answer from any gurus as yet. Please help - I am afraid I might lose my whole system.
Thanks lotvic - I searched and thought I was missing something !
Bearing in mind that not having seen your other question, I only have what you wrote today, to go on. So with this in mind I just ran a web search regarding your 'Invalid Boot.ini' problem and at CLICK HERE I found the following...
"Invalid Boot.ini" or "Windows could not start" error messages when you start your computer.
When you start your computer after you upgrade to Microsoft Windows XP, you may receive one or both of the following error messages:
Windows could not start because the following file is missing or corrupt:
This issue may occur if the Boot.ini file is missing, damaged, or contains incorrect entries.
To resolve this issue, start the computer from the Windows XP CD, start the Recovery Console, and then use the Bootcfg.exe tool to rebuild the Boot.ini file. To do this, follow these steps:
Configure the computer to start from the **CD-ROM** or **DVD-ROM** drive. For information about how to do this, see your computer documentation, or contact your computer manufacturer. Insert the **Windows XP CD-ROM** into your **CD-ROM** or **DVD-ROM** drive, and then restart your computer. When you receive the "**Press any key to boot from CD**" message, press a key to start your computer from the Windows XP CD-ROM. When you receive the "**Welcome to Setup**" message, press R to start the Recovery Console. If you have a dual-boot or multiple-boot computer, select the installation that you have to use from the Recovery Console. When you are prompted, type the administrator password, and then press **ENTER**. At the command prompt, type bootcfg /list, and then press **ENTER**. The entries in your current Boot.ini file appear on the screen. At the command prompt, type bootcfg /rebuild, and then press **ENTER**. This command scans the hard disks of the computer for Windows XP, Microsoft Windows 2000, or Microsoft Windows NT installations, and then displays the results. Follow the instructions that appear on the screen to add the Windows installations to the Boot.ini file. For example, follow these steps to add a Windows XP installation to the Boot.ini file: When you receive a message that is similar to the following message, press **Y**: Total Identified Windows Installs: **1**  **C:\Windows** Add installation to boot list? (**Yes/No/All**) You receive a message that is similar to the following message: **Enter Load Identifier** This is the name of the operating system. When you receive this message, type the name of your operating system, and then press **ENTER**. This is either Microsoft Windows XP Professional or Microsoft Windows XP Home Edition. You receive a message that is similar to the following: **Enter OS Load options**
When you receive this message, type /fastdetect and then press ENTER.
Note The instructions that appear on your screen may be different, depending on the configuration of your computer. Type **exit** then press **ENTER** to quit Recovery Console.
Your computer restarts, and the updated boot list appears when you receive the "Please select the operating system to start" message.
