Solve : Having terrible boot problems, please help!?

Answer» <html><body><p>Hey guys,<br/><br/>well here's the scoop;<br/>I created a partition a while back with vista 64bit and windows xp 32 bit. I installed xp first to create the partition, then installed vista on the other half of the hard drive. Everything worked fine. When I would start up my computer I was prompted for which OS I would like to boot from. However I had to reformat recently and decided to start new with Vista 64 bit and xp 64 bit. I started by reformatting my vista first, then went and reformat xp with my 64 bit version. Now when I start up it automatically boots into xp everytime. I tried editing the boot file in xp but i simply <a href="https://interviewquestions.tuteehub.com/tag/don-t-246903" style="font-weight:bold;" target="_blank" title="Click to know more about DONT">DONT</a> know what line to add or what not to. i messed with it a bit and managed to give myself the option to boot from vista, but now when i try it says something along the lines of "ntoskrnl missing" and it cant start. I'm not sure if I even edited the boot file correctly. I'll post more details of what specifically I have in the boot file when I get home from <a href="https://interviewquestions.tuteehub.com/tag/work-20377" style="font-weight:bold;" target="_blank" title="Click to know more about WORK">WORK</a>. I figured, i'll just boot from cd and rebuild the file, or wipe everything clean and start over, but now I dont even get prompted to boot from cd. it goes directly to my os select screen now. Can anyone assist? I would greatly appreciate it.<br/><br/>-PaulWhen you start the computer, do you see a message like "Press Delete to enter setup" (could also be F2 key instead of Del)?<br/><br/>As soon as u see that, press that. This will get you into the BIOS.<br/>Here in the BIOS you can change your boot sequence.Yeah, I changed the boot priority to my cd rom first, but still, no option to boot from cd. It goes right to OS select.You said you messed with the boot.ini file. <br/>Could you post that file here?certainly. when I get back from work i'll post it up here. thanks for your effort! <a href="https://interviewquestions.tuteehub.com/tag/although-7380138" style="font-weight:bold;" target="_blank" title="Click to know more about ALTHOUGH">ALTHOUGH</a> the option to boot from cd stopped appearing right after xp6d bit was installed, before boot.ini was modified.XP here-----------------------Vista here<br/>When you re-installed XP the boot sector is recreated,,,therefore all your boot files related to Vista are GONE as well.<br/>You could try doing a repair install of Vista but i think for it to work properly you are looking at starting over again.<br/><br/>Please re-state how exactly you did this step by step as well as defining your drives/partitions layout...ok, I installed Windows XP 32 bit. Before I started installing it I partitioned the drive(C:) down the middle so it was now C: and E: at ~150G each. I Installed xp to drive C:. After Installation was done I restarted with vista ultimate 64 bit in the drive, boot from cd, and installed it to drive E:. Everything <a href="https://interviewquestions.tuteehub.com/tag/ran-618623" style="font-weight:bold;" target="_blank" title="Click to know more about RAN">RAN</a> fine, until recently I had to reformat my vista. I decided to reformat my xp as well so that I could run xp 64 bit. I reformat my vista with the same 64 bit version as before. When it was finished I restarted, put in xp professional 64 bit, boot from cd and reformat my xp to xp professional 64 bit. I started installing drivers for my motherboard, it restarted and booted immediately to xp. No prompt to boot from cd, no OS select, just directly to xp. I downloaded some boot managers because i didn't want to mess with the boot.ini as i had no previous experience with it. The boot managers were even more confusing, they didn't recognize my partition, and I had to work loops around it just to find my partition with vista on it. I uninstalled it and did a little research on boot.ini commands. So as of right now this is what I have in the boot editor on windows xp professional 64bit:<br/><br/>[boot loader]<br/>timeout=60<br/>default=multi(0)disk(0)rdisk(0)partition(0)\WINDOWS<br/>[operating systems]<br/>multi(0)disk(0)rdisk(0)partition(0)\WINDOWS="Windows Vista Ultimate x64 Edition" /noexecute=optin /fastdetect<br/>multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Professional x64 Edition" /noexecute=optin /fastdetect<br/><br/>Previous to how I have it set now, I had Vista set to partition(2). The computer would just restart when I would select it. I figured that was the wrong partition so I set it to partition(0) and when I select vista, it boots up and I get an error saying that ntoskrnl.exe is corrupt or missing and needs to be replaced or repaired. I checked the E: drive from XP and found that system 32 still has the file ntoskrnl.exe. So it must just be corrupt. However ever since xp professional 64 bit I am not prompted to boot from cd, regardless of the fact that my boot priority is set with cd-rom at the top of the list. <br/><br/>Hope that that's thorough enough! Any help would be so appreciated. Thanks!<br/><br/>-PaulOK.<br/>First of all is the XP install having any hiccups at all ? ?<br/>Problems booting, hanging or shutting down ? ?<br/>If so i would run a <a href="http://www.michaelstevenstech.com/XPrepairinstall.htm">Repair Install of XP</a><br/><br/>Then i would DLoad and install VistaBootPro....wipe the Vista partition and use it to do the Vista install.<br/>Do you have a copy of the original bootini to revert to ? ?<br/>If so do this before the Vista install. Vista handles the boot sector a bit differently than other flavors of Windows but if the XP install is intact there is no reason this shouldn't work...Untill recently I had a XP64/Vista Business dual boot.<br/>I already had XP64 installed on my C drive, and installed Vista on a completely different drive.<br/><br/>Now in my boot.ini file on the C drive, it just had one line, only the XP line.<br/>The real boot file came from Vista, who had created the dual boot file.<br/><br/>The standard OS to boot would be Vista (you know, the OS that starts after 30 secs).<br/>But after downloading EasyBCD and installing it in Vista, I could easily change that.<br/><br/>So, my point:<br/><a href="https://interviewquestions.tuteehub.com/tag/changing-246341" style="font-weight:bold;" target="_blank" title="Click to know more about CHANGING">CHANGING</a> the boot.ini file (from your xp partition) wouldn't do you any good, since Vista creates the dualboot.<br/><br/>Well, thats how it was in my case.<br/><br/><br/><br/></p></body></html>
