Hi you clever lot on here. tnx here,messing again. The other day I got myself a e-SATA to SATA cable. It works a treat. The transfer rate is much quicker than USB2 (I dont have USb3). So I got to thinking I could install Windows 7 off a HDD connected via the e-SATA port. Using DISKPART i formatted a 60 gig SATA HDD and copied the installation files to the drive. I restarted my machine,slung in my spare 80gig SATA HDD which I test stuff out on and booted up from the e-SATA driver. Wow it installed Windows pretty damn quick. But.... I get BOOTMGR missing when I unplug the e-SATA and boot from the 80 gig SATA HDD. Plug the e-SATA drive back in and it boots into Windows. I have tried unpluging e-SATA and booting from a dvd to repair the boot but it wont work. Dont know why. What I would like to know......Is there a way to install W7 off a HDD onto an internal HDD without getting any BOOTMGR problems. I have not tried formatting the e-SATA into Fat32,just NTFS....Would this help somehow. Is there a way to make the e-SATA "READ ONLY". What I dont understand is why would windows load the bootMGR onto the drive the install files are on. It just seems daft whay that happens. Hope this makes sence. Any tips,advice ?? Cheers..
