First try installing the program in its default location, check if that makes any difference. Second- use 0.2.1, third- try it on Vista or XP. I have never tested it on Windows 7, there a a few external tools used and ALL them have to support 7. In other words- no reliable support for now of Windows 7. Now i tryd out a complet install. First i slipstreamed all hotfixes, WMP11, flash player, WUA, etc. Then added driverpacks from driverpacks.net (sata, lan, chipset, cpu). After that i made the USB pen with 0.2.1 under W7. (SP3 comp mode, admin rights) The pen boots fine. In text mode setup works fine all things, expect some unattended settings. In the ~BT folder, this is the first part of the winnt.sif file: [Data] AutoPartition="0" UnattendedInstall="Yes" MsDosInitiated="1" floppyless="1" [GuiUnattended] AutoLogon = Yes AdminPassword=* EncryptedAdminPassword=NO OEMSkipRegional=1 TimeZone=95 OemSkipWelcome=1 DetachedProgram=".\system32\cmd.exe" Arguments="/Q /C FOR /F %I IN (%SystemRoot%\SYSTEM32\$WINNT$.INF) DO (FOR %J IN (%I$OEM$) DO (IF EXIST %J (start /min /D%J Drivers.cmd)))" So the text mode is not unattended. (My XP is fully unattended) This is the ~LS/i386 folder's winnt.sif file: [Data] AutoPartition=0 UnattendedInstall="Yes" MsDosInitiated=No [Unattended] UnattendMode=DefaultHide OemSkipEula=Yes Unattendswitch=Yes WaitForReboot = No TargetPath=\WINDOWS Hibernation = No MaximumDataStorePercentOfDisk = 5 RestorePointLife = 30 FileSystem=* OemPreinstall=Yes DriverSigningPolicy=Ignore NonDriverSigningPolicy=Ignore OemPnpDriversPath="D\C\A1;D\C\A2;D\C\AM2;D\C\AM3;D\C\AM4;D\C\AM5;D\C\AM6;D\C\AM7;D\C\AT;D\C\AU;D\C\D;D\C\F;D\C\H;D\C\I1;D\C\I2\1;D\C\I2\2;D\C\I2\3;D\C\I2\4;D\C\I3\1;D\C\I3\2;D\C\I3\3;D\C\I4;D\C\I5;D\C\IN;D\C\IT;D\C\N1;D\C\N2;D\C\N3;D\C\N4;D\C\SM;D\C\T;D\C\V1\2K;D\C\V1\2K3;D\C\V1\XP;D\C\V2;D\CPU;D\L\3A;D\L\3B;D\L\3C;D\L\3D;D\L\3E;D\L\3F;D\L\AC1;D\L\AC2;D\L\AC4;D\L\AC5;D\L\AC6;D\L\AC7;D\L\AD1;D\L\AD2;D\L\AG;D\L\AL;D\L\AM1;D\L\AM2;D\L\AM3;D\L\AS1;D\L\AS2;D\L\AS3;D\L\AS4;D\L\AS5;D\L\AS6;D\L\AT1;D\L\AT2;D\L\AT3;D\L\ATE;D\L\AU;D\L\B1;D\L\B2;D\L\B3;D\L\B4;D\L\BE1;D\L\BF;D\L\BU1;D\L\BU2;D\L\BU3;D\L\C1;D\L\CO1;D\L\CO2;D\L\CO3;D\L\CO5;D\L\D10;D\L\D2;D\L\D3;D\L\D4;D\L\D5;D\L\D6;D\L\D7;D\L\D8;D\L\D9;D\L\DA1;D\L\DA2;D\L\DA3;D\L\HP;D\L\I1;D\L\I2;D\L\IC1;D\L\IC2;D\L\L1;D\L\L2;D\L\L4;D\L\L5;D\L\L6;D\L\L7;D\L\L8;D\L\M;D\L\MI;D\L\MO;D\L\N1;D\L\N10;D\L\N2;D\L\N3;D\L\N4;D\L\N5;D\L\N6;D\L\N7;D\L\N8;D\L\N9;D\L\ND1;D\L\NS1;D\L\NV;D\L\NV3;D\L\NV3\PreNRM\Win2K;D\L\NV3\PreNRM\WinXP;D\L\NV4;D\L\NV5;D\L\NV5A;D\L\NV6;D\L\NV6A;D\L\NV7;D\L\NV8;D\L\O1;D\L\O2;D\L\O3;D\L\O4;D\L\O5;D\L\O6;D\L\O8;D\L\R1;D\L\R2;D\L\R3;D\L\R4;D\L\SB1;D\L\SB2;D\L\SIL;D\L\SIS;D\L\SIS2;D\L\SM1;D\L\SM2;D\L\SM3;D\L\SM4;D\L\SM6;D\L\SM7;D\L\SM8;D\L\SM9;D\L\SU1;D\L\SU5;D\L\SU7;D\L\SU8;D\L\SU9;D\L\SUC;D\L\U1;D\L\U3;D\L\U4;D\L\U5;D\L\V1;D\L\V2;D\L\V3;D\L\X1;D\L\X2;D\L\Z;D\M\3;D\M\3B;D\M\3C;D\M\A;D\M\A2;D\M\A3;D\M\A4;D\M\A5;D\M\A6;D\M\A7;D\M\A8;D\M\AD1;D\M\AD2;D\M\AD3;D\M\AD4;D\M\AD5;D\M\AD6;D\M\AD7;D\M\AD8;D\M\AD9;D\M\ADA;D\M\ADB;D\M\ADC;D\M\AM;D\M\AM1;D\M\AM2;D\M\AM3;D\M\AR;D\M\AT;D\M\AU;D\M\AU2;D\M\AU3;D\M\B;D\M\C;D\M\C1;D\M\C2;D\M\C3;D\M\D;D\M\D1;D\M\E;D\M\H;D\M\H1;D\M\H10;D\M\H1S;D\M\H2;D\M\H3;D\M\H3K;D\M\H3S;D\M\H5;D\M\H6;D\M\H6S;D\M\H7;D\M\H7S;D\M\H8;D\M\H9;D\M\H9S;D\M\I1;D\M\I2;D\M\I3;D\M\I4;D\M\I5;D\M\I6;D\M\IB1;D\M\IB2;D\M\IB3;D\M\IB6;D\M\INI;D\M\IT;D\M\J;D\M\L;D\M\L1;D\M\L10;D\M\L11;D\M\L2;D\M\L3;D\M\L4;D\M\L5;D\M\L6;D\M\L7;D\M\L8;D\M\L9;D\M\M;D\M\M2;D\M\M3;D\M\M4;D\M\NV123;D\M\NV4;D\M\NV4IN;D\M\NV5;D\M\NV6;D\M\NVTM;D\M\P;D\M\P\K;D\M\P\S;D\M\P1;D\M\P1K;D\M\P1S;D\M\P2;D\M\P2\K;D\M\P2S;D\M\P3;D\M\P4;D\M\P4K;D\M\P4S;D\M\P5;D\M\P6;D\M\P7;D\M\P8;D\M\P9;D\M\PA;D\M\PAS;D\M\PC;D\M\Q;D\M\Q2;D\M\Q3;D\M\Q4;D\M\S;D\M\S2;D\M\S2A;D\M\S3;D\M\S4;D\M\S5;D\M\S7;D\M\S7A;D\M\S7B;D\M\S8;D\M\S9;D\M\SA;D\M\SA2;D\M\SB;D\M\SB2;D\M\SB3;D\M\SB4;D\M\SB5;D\M\SC;D\M\SC2;D\M\SC3;D\M\SC4;D\M\SC5;D\M\SIS;D\M\SIS1;D\M\SIS2;D\M\SIS3;D\M\V1;D\M\V2;D\M\V3;D\M\VM" [GuiUnattended] AutoLogon = Yes AdminPassword=* EncryptedAdminPassword=NO OEMSkipRegional=1 TimeZone=95 OemSkipWelcome=1 DetachedProgram=".\system32\cmd.exe" Arguments="/Q /C FOR /F %I IN (%SystemRoot%\SYSTEM32\$WINNT$.INF) DO (FOR %J IN (%I$OEM$) DO (IF EXIST %J (start /min /D%J Drivers.cmd)))" The text mode is not unattended, it's not a problem, because if it's unattended, we lose the recovery console option. But the second part of the install, it wasn't lanched my Drivers.cmd file in the start. It's urgent, because in this part of the setup, we can only lanch an application with this methode: DetachedProgram=".\system32\cmd.exe" Arguments="/Q /C FOR /F %I IN (%SystemRoot%\SYSTEM32\$WINNT$.INF) DO (FOR %J IN (%I$OEM$) DO (IF EXIST %J (start /min /D%J Drivers.cmd)))" Expect that, all things works fine, my XP is installed succesfull, and was a quite fast process. - Nice work. I uploaded my log file... link ---------------- And maybe an extra function for your program: run easyboot cd menü from usb: (compatible with your usb maker prog) yust add these lines to the winsetup.lst file: title Start EasyBoot find --set-root --ignore-floppies /iso/mycd.iso map /iso/mycd.iso (hd32) map --hook chainloader (hd32) boot And of corse, put a file called mycd.iso to the iso folder to the pen.
