Hey all, I am having a problem with my sister's machine, in that it hangs on the Pentium 4 logo for 10+ minutes, before finally booting up and working fine. Sometimes, it goes past the logo quickly, but then starts to boot up with the message 'disk boot failure, please insert system disk...', and I have to restart it otherwise it just stays on this message. As far as I know this started after I transferred a load of files onto her machine when I was reformatting mine, then I restarted the get the network back after installing Windows again on my machine, then it started with the hanging on startup. I deleted these files but it hasn't changed anything. Does anyone have any advice? I have run the disk check tool that checks the disk during startup, and everything in the system itself looks good, no loose wires etc.
