 ## Troubleshooting Build Issues
 
 ### Error: "Not enough disk space"
-- Free up at least 10GB
-- Build uses `/tmp/secureos-build` (needs 5-8GB temp space)
+**Solution:**
+- Free up at least 15GB (20GB recommended)
+- Build uses `/tmp/secureos-build` (needs 8-12GB temp space)
+- Check with: `df -h /tmp`
 
 ### Error: "Permission denied"
-- Must run with `sudo`
-- Check file permissions
+**Solution:**
+- Must run with `sudo` or as root
+- Check file permissions with: `ls -la build-iso.sh`
+- Make executable: `chmod +x build-iso.sh`
 
 ### Error: "Failed to download packages"
-- Check internet connection
+**Solution:**
+- Check internet connection: `ping archive.ubuntu.com`
 - Try different mirror in sources.list
+- Update package lists: `sudo apt-get update`
 - Retry the build
 
+### Error: "This script must be run as root"
+**Solution:**
+- Run with sudo: `sudo ./build-iso.sh`
+- Or switch to root: `sudo su -` then run the script
+
 ### Build Hangs or Freezes
-- Check system resources (RAM, CPU)
+**Solution:**
+- Check system resources: `htop` or `free -h`
 - Kill and restart: `sudo killall debootstrap`
 - Clear temp: `sudo rm -rf /tmp/secureos-build`
+- Check logs: `tail -f build.log`
 
 ### Error: "Invalid GPG signature"
+**Solution:**
 - Update GPG keys:
   ```bash
   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [KEY_ID]
   ```
 
+### Error: "grub-mkrescue: command not found"
+**Solution:**
+- Install GRUB tools:
+  ```bash
+  sudo apt-get install grub-pc-bin grub-efi-amd64-bin
+  ```
+
+### Error: "mksquashfs: command not found"
+**Solution:**
+- Install squashfs-tools:
+  ```bash
+  sudo apt-get install squashfs-tools
+  ```
+
+### Python Dependencies Missing (v5.0.0 features)
+**Solution:**
+- Install Python packages:
+  ```bash
+  sudo apt-get install python3-pip python3-dev
+  sudo pip3 install numpy scikit-learn cryptography pynacl
+  ```
+
+### Build fails during chroot
+**Solution:**
+- Check if filesystems are mounted: `mount | grep secureos-build`
+- Unmount manually:
+  ```bash
+  sudo umount /tmp/secureos-build/chroot/{dev/pts,sys,proc,run,dev}
+  ```
+- Clean and retry
+
+## Dependency Management
+
+### Required Build Dependencies
+
+The build scripts automatically check and install required dependencies. These include:
+
+- **debootstrap**: Bootstrap base system
+- **squashfs-tools**: Create compressed filesystem
+- **xorriso**: Create ISO images
+- **isolinux**: Boot loader for ISO
+- **syslinux-efi**: EFI boot support
+- **grub-pc-bin**: GRUB bootloader (BIOS)
+- **grub-efi-amd64-bin**: GRUB bootloader (UEFI)
+- **mtools**: DOS filesystem tools
+- **dosfstools**: FAT filesystem tools
+- **git**: Version control
+
+### Manual Dependency Installation
+
+If you prefer to install dependencies manually before building:
+
+```bash
+sudo apt-get update
+sudo apt-get install -y \
+    debootstrap \
+    squashfs-tools \
+    xorriso \
+    isolinux \
+    syslinux-efi \
+    grub-pc-bin \
+    grub-efi-amd64-bin \
+    mtools \
+    dosfstools \
+    git \
+    python3 \
+    python3-pip
+```
+
+### Python Dependencies for v5.0.0 Features
+
+```bash
+sudo pip3 install numpy scikit-learn cryptography pynacl
+```
+
 ## Build Cleanup
 
 After successful build:
 ```bash
-# Temporary build files are auto-cleaned
+# Temporary build files are auto-cleaned by the script
 # But you can manually clean with:
 sudo rm -rf /tmp/secureos-build
+
+# Clean all build artifacts:

+## Build Verification
+
+After building, verify the ISO integrity:
+
+### Automated Verification (Recommended)
+
+Run the verification script to perform comprehensive checks:
+```bash
+./verify-iso.sh
+```
+
+This script checks:
+- ISO file existence and size
+- SHA256 and MD5 checksums
+- ISO format and bootability
+- Essential ISO contents (kernel, initrd, filesystem)
+- Build log for errors
+
+### Manual Verification
+
+Check the SHA256 checksum manually:
+```bash
+cd iso-build
+sha256sum -c SecureOS-1.0.0-amd64.iso.sha256
+```
+
+Expected output:
+```
+SecureOS-1.0.0-amd64.iso: OK
